app/vmauth: add support for hot standby mode via first_available load balancing policy
vmauth in `hot standby` mode sends requests to the first url_prefix while it is available.
If the first url_prefix becomes unavailable, then vmauth falls back to the next url_prefix.
This allows building highly available setup as described at https://docs.victoriametrics.com/vmauth.html#high-availability

lib/promscrape: show -promscrape.cluster.memberNum values for vmagent instances, which scrape the given dropped target at /service-discovery page
The /service-discovery page contains the list of all the discovered targets
after the commit 487f6380d0 on all the vmagent instances
in cluster mode ( https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets ).

This commit improves debuggability of targets in cluster mode by providing a list of -promscrape.cluster.memberNum
values per each target at /service-discovery page, which has been dropped becasue of sharding,
e.g. if this target is scraped by other vmagent instances in the cluster.

Substitute O(N^2) algorithm for exposing the `vm_promscrape_scrape_pool_targets` metric

app/vmselect: properly adjust the lower bound for the time range where raw samples must be selected for default_rollup() function
Previously the lower bound could be too small, which could result in missing values at the beginning of the graph
for default_rollup() function. This function is automatically applied to all the series selectors if they aren't
explicitly wrapped into a rollup function - see https://docs.victoriametrics.com/MetricsQL.html#implicit-query-conversions

While at it, properly take into account `-search.minStalenessInterval` command-line flag when adjusting
the lower bound for the selected time range.

app/vmagent: code cleanup for Kafka and Google PubSub consumers / producers
- Add links to relevant docs into descriptions for every -kafka.* and -gcp.pubsub.* command-line flags.
- Wait until message processing goroutines are stopped before returning from gcppubsub.Stop().
- Prevent from multiple calls to Init() without Stop().
- Drop message if tenantID cannot be parsed properly.
- Take into account tenantID for all the supported message formats.
- Support gzip-compressed messages for graphite format.
- Use exponential backoff sleep when the message cannot be pushed to remote storage systems
  because of disabled on-disk persistence - https://docs.victoriametrics.com/vmagent.html#disabling-on-disk-persistence
- Unblock from sleep as soon as Stop() is called. Previously the sleep could take up to 2 seconds after Stop() is called.
- Remove unused globalCtx and initContext from app/vmagent/remotewrite/gcppubsub
- Mention Google PubSub support at docs/enterprise.md
- Make Google PubSub docs more clear at docs/vmagent.md

app/vmselect: do not limit concurrency for static and fast queries
Previously concurrency for static and fast queries was limited with the -search.maxConcurrentRequests

since `vmui` and these pages couldn't be opened on overloaded vmselect.

Previously the /service-discovery page didn't show targets dropped because of sharding
( https://docs.victoriametrics.com/vmagent.html#scraping-big-number-of-targets ).

Show also the reason why every target is dropped at /service-discovery page.
This should improve debuging why particular targets are dropped.

While at it, do not remove dropped targets from the list at /service-discovery page
until the total number of targets exceeds the limit passed to -promscrape.maxDroppedTargets .
Previously the list was cleaned up every 10 minutes from the entries, which weren't updated
for the last minute. This could complicate debugging of dropped targets.

app/vmagent: follow-up for 090cb2c9de
- Add Try* prefix to functions, which return bool result in order to improve readability and reduce the probability of missing check
  for the result returned from these functions.

- Call the adjustSampleValues() only once on input samples. Previously it was called on every attempt to flush data to peristent queue.

- Properly restore the initial state of WriteRequest passed to tryPushWriteRequest() before returning from this function
  after unsuccessful push to persistent queue. Previously a part of WriteRequest samples may be lost in such case.

- Add -remoteWrite.dropSamplesOnOverload command-line flag, which can be used for dropping incoming samples instead
  of returning 429 Too Many Requests error to the client when -remoteWrite.disableOnDiskQueue is set and the remote storage
  cannot keep up with the data ingestion rate.

- Add vmagent_remotewrite_samples_dropped_total metric, which counts the number of dropped samples.

- Add vmagent_remotewrite_push_failures_total metric, which counts the number of unsuccessful attempts to push
  data to persistent queue when -remoteWrite.disableOnDiskQueue is set.

- Remove vmagent_remotewrite_aggregation_metrics_dropped_total and vm_promscrape_push_samples_dropped_total metrics,
  because they are replaced with vmagent_remotewrite_samples_dropped_total metric.

- Update 'Disabling on-disk persistence' docs at docs/vmagent.md

- Update stale comments in the code

app/vmagent: allow to disabled on-disk persistence (#5088)
* app/vmagent: allow to disabled on-disk queue
Previously, it wasn't possible to build data processing pipeline with a
chain of vmagents. In case when remoteWrite for the last vmagent in the
chain wasn't accessible, it persisted data only when it has enough disk
capacity. If disk queue is full, it started to silently drop ingested
metrics.

New flags allows to disable on-disk persistent and immediatly return an
error if remoteWrite is not accessible anymore. It blocks any writes and
notify client, that data ingestion isn't possible.

Main use case for this feature - use external queue such as kafka for
data persistence.
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2110

* adds test, updates readme

* apply review suggestions

* update docs for vmagent

* makes linter happy

lib/protoparser: decrease import.maxLineLen from 100MB to 10MB (#5364)
Tests showed that importing a single line with 70MB size takes 5.3GiB
RSS memory for VictoriaMetrics single-node.
In the scenario when user exports and imports data from one VM to another,
it could possibly lead to OOM exception for destination VM.

Importing a single line with 16MB size taks 1.3GiB RSS memory.
Hence, the limit for `import.maxLineLen` was decreased from 100MB to 10MB
to improve reliability of VictoriaMetrics during imports.

lib/protoparser/promremotewrite: fall back to zstd decoding if Snappy-decoding fails (#5344)
This case is possible after the following steps:
1. vmagent successfully performed handshake with the -remoteWrite.url and the remote storage supports zstd-compressed data.
2. remote storage became unavailable or slow to ingest data, vmagent compressed the collected data into blocks with zstd and puts these blocks to persistent queue on disk.
3. vmagent restarts and the remote storage is unavailable during the handshake, then vmagent falls back to Snappy compression.
4. vmagent starts sending zstd-compressed data from persistent queue to the remote storage, while falsely advertizing it sends Snappy-compressed data.
5. The remote storage receives zstd-compressed data and fails unpacking it with Snappy.

The solution is the same as 12cd32fd75, just fall back to zstd decompression if Snappy decompression fails.

app/vmselect/promql: properly handle duplicate series when merging cached results with the results obtained from the database
evalRollupFuncNoCache() may return time series with identical labels (aka duplicate series)
when performing queries satisfying all the following conditions:

- It must select time series with multiple metric names. For example, {__name__=~"foo|bar"}
- The series selector must be wrapped into rollup function, which drops metric names. For example, rate({__name__=~"foo|bar"})
- The rollup function must be wrapped into aggregate function, which has no streaming optimization.
  For example, quantile(0.9, rate({__name__=~"foo|bar"})

In this case VictoriaMetrics shouldn't return `cannot merge series: duplicate series found` error.
Instead, it should fall back to query execution with disabled cache.

Also properly store the merged results. Previously they were incorrectly stored because of a typo
introduced in the commit 41a0fdaf39

This allows hiding VictoriaMetrics components behind proxies with arbitrary path prefixes.
For example, vmagent HTTP handlers can be served via /vmagent/ path prefix:

- http://proxy/vmagent/targets
- http://proxy/vmagent/service-discovery

The path prefix can be arbitrary. For example, below are vmagent urls
for /tenantID/vmagent/ path prefix:

- http://proxy/tenantID/vmagent/targets
- http://proxy/tenantID/vmagent/service-discovery

app/vmauth: properly pass Host header to backends
Previously the `Host` header was remained unchanged when passing it in requests to backends.
This may improperly work if the backend uses host-based routing.

While at it, allows http/2.0 requests to backends. While VictoriaMetrics components
do not accept http/2.0 requests, other backends can require such requests.

  This fixes handling of the limit on the number of connection, which can be established per each backend
  via -maxIdleConnsPerBackend command-line flag. This limit stopped working after 323f3720ed

- Add docs about backend TLS setup at https://docs.victoriametrics.com/vmauth.html#backend-tls-setup

- Add ability to disable backend TLS verification for all the users via -backend.tlsInsecureSkipVerify command-line flag.
  This flag may be useful when -auth.config contains big number of users, and every user must disable backend TLS verification.

- Add ability to specify TLS Root CA via tls_ca_file option at per-user basis and via -backend.tlsCAFile command-line flag
  across all the users.

lib/blockcache: do not cache entries, which were attempted to be accessed 1 or 2 times
Previously entries which were accessed only 1 time weren't cached.
It has been appeared that some rarely executed heavy queries may read indexdb block twice
in a row instead of once. There is no need in caching such a block then.
This change should eliminate cache size spikes for indexdb/dataBlocks when such heavy queries are executed.

Expose -blockcache.missesBeforeCaching command-line flag, which can be used for fine-tuning
the number of cache misses needed before storing the block in the caching.

app/vmselect/promql: optimize repeated SLI-like instant queries with lookbehind windows >= 1d
Repeated instant queries with long lookbehind windows, which contain one of the following rollup functions,
are optimized via partial result caching:

- sum_over_time()
- count_over_time()
- avg_over_time()
- increase()
- rate()

The basic idea of optimization is to calculate

  rf(m[d] @ t)

as

  rf(m[offset] @ t) + rf(m[d] @ (t-offset)) - rf(m[offset] @ (t-d))

where rf(m[d] @ (t-offset)) is cached query result, which was calculated previously

The offset may be in the range of up to 1 hour.

lib/promauth: follow-up for e16d3f5639
- Make sure that invalid/missing TLS CA file or TLS client certificate files at vmagent startup
  don't prevent from processing the corresponding scrape targets after the file becomes correct,
  without the need to restart vmagent.
  Previously scrape targets with invalid TLS CA file or TLS client certificate files
  were permanently dropped after the first attempt to initialize them, and they didn't
  appear until the next vmagent reload or the next change in other places of the loaded scrape configs.

- Make sure that TLS CA is properly re-loaded from file after it changes without the need to restart vmagent.
  Previously the old TLS CA was used until vmagent restart.

- Properly handle errors during http request creation for the second attempt to send data to remote system
  at vmagent and vmalert. Previously failed request creation could result in nil pointer dereferencing,
  since the returned request is nil on error.

- Add more context to the logged error during AWS sigv4 request signing before sending the data to -remoteWrite.url at vmagent.
  Previously it could miss details on the source of the request.

- Do not create a new HTTP client per second when generating OAuth2 token needed to put in Authorization header
  of every http request issued by vmagent during service discovery or target scraping.
  Re-use the HTTP client instead until the corresponding scrape config changes.

- Cache error at lib/promauth.Config.GetAuthHeader() in the same way as the auth header is cached,
  e.g. the error is cached for a second now. This should reduce load on CPU and OAuth2 server
  when auth header cannot be obtained because of temporary error.

- Share tls.Config.GetClientCertificate function among multiple scrape targets with the same tls_config.
  Cache the loaded certificate and the error for one second. This should significantly reduce CPU load
  when scraping big number of targets with the same tls_config.

- Allow loading TLS certificates from HTTP and HTTPs urls by specifying these urls at `tls_config->cert_file` and `tls_config->key_file`.

- Improve test coverage at lib/promauth

- Skip unreachable or invalid files specified at `scrape_config_files` during vmagent startup, since these files may become valid later.
  Previously vmagent was exitting in this case.

Previously yaml parser wasn't accepting string values for these fields,
because it was mistakenly expecting a list of uint8 values instead.

app/vmalert: follow-up after c9375cac5e
c9375cac5e

Descriptions were updated in attempt to make it more clear for readers,
re-phrasing and linking missing docs.

`eval_delay` was added to tests to verify it can be unmarshalled.

`eval_delay` is now applied before timestamp alignment to make it more predictable.
Before, if delay < interval the timestamp won't be aligned.

`eval_delay` and `eval_offset` was added to API output.

`PreviouslySentSeriesToRW` converted to private `previouslySentSeriesToRW`.

docs: use https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest instead of https://github.com/VictoriaMetrics/VictoriaMetrics/releases link where needed
The https://github.com/VictoriaMetrics/VictoriaMetrics/releases link may show non-latest
releases at the top, such as LTS releases or VictoriaLogs releases.
So it is better to use https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest link,
which always redirect to the latest available release of VictoriaMetrics.

app/vmselect: limit the number of parallel workers by 32 (#5195)
* app/vmselect: limit the number of parallel workers by 32

The change should improve performance and memory usage during query processing
on machines with big number of CPU cores. The number of parallel workers for
query processing is controlled via `-search.maxWorkersPerQuery` command-line flag.
By default, the number of workers is limited by the number of available CPU cores,
but not more than 32. The limit can be increased via `-search.maxWorkersPerQuery`.

Signed-off-by: hagen1778 <roman@victoriametrics.com>

* wip

- The `-search.maxWorkersPerQuery` command-line flag doesn't limit resource usage,
  so move it from the `resource usage limits` to `troubleshooting` chapter at docs/Single-server-VictoriaMetrics.md

- Make more clear the description for the `-search.maxWorkersPerQuery` command-line flag

- Add the description of `-search.maxWorkersPerQuery` to docs/Cluster-VictoriaMetrics.md

- Limit the maximum value, which can be passed to `-search.maxWorkersPerQuery`, to GOMAXPROCS,
  because bigger values may worsen query performance and increase CPU usage

- Improve the the description of the change at docs/CHANGELOG.md. Mark it as FEATURE instead of BUGFIX,
  since it is closer to a feature than to a bugfix.

This query drops temperature series with all the values bigger than 30 on the selected time range,
while replacing gaps in the remaining series with 40.

The query without drop_empty_series:

  (temperature <= 30) default 40

would leave all the temperature series with all the values bigger than 30 on the selected time range,

Reason for revert: relative links do not work properly at GitHub code
and at GitHub wiki. For example, the following page contains broken links
before reverting this commit:

https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/VictoriaLogs/CHANGELOG.md

It is always better to use absolute links thank relative links, since the page contents
can be copy-n-pasted to other pages, which are located in vastly different directories,
and all the links will remain working.

app/{vmagent,vminsert}: follow-up for NewRelic data ingestion protocol support
This is a follow-up for f60c08a7bd

Changes:

- Make sure all the urls related to NewRelic protocol start from /newrelic . Previously some urls were started from /api/v1/newrelic

- Remove /api/v1 part from NewRelic urls, since it has no sense

- Remove automatic transformation from CamelCase to snake_case for NewRelic labels and metric names,
  since it may complicate the transition from NewRelic to VictoriaMetrics. Preserve all the metric names and label names,
  so users could query metrics and labels by the same names which are used in NewRelic.
  The automatic transformation from CamelCase to snake_case can be added later as a special action for relabeling rules if needed.

- Properly update per-tenant data ingestion stats at app/vmagent/newrelic/request_handler.go . Previously it was always zero.

- Fix NewRelic urls in vmagent when multitenant data ingestion is enabled. Previously they were mistakenly started from `/`.

- Document NewRelic data ingestion url at docs/Cluster-VictoriaMetrics.md

- Remove superflouos memory allocations at lib/protoparser/newrelic

- Improve tests at lib/protoparser/newrelic/*

lib/license: cleanups and prettifications for log messages and docs related to licensing
- Make more clear the docs at docs/enterprise.md, so readers could figure out faster
  on how to obtain enterprise key and how to pass it to VictoriaMetrics Enterprise components.

- Fix examples at docs/enterprise.md, which were referring to non-existing `-license-file` command-line flag.
  The `-licenseFile` command-line flag must be used instead.

- Improve the description of `-license*` command-line flags, so users could understand
  faster how to use them.

- Improve the warning message, which is emitted when the deprecated -eula command-line flag is passed,
  so the user could figure out how to switch faster to -license* command-line flags.

- Disallow running VictoriaMetrics components with both -license and -licenseFile command-line flags.

- Disallow running VictoriaMetrics components when -licensFile points to an empty file.

- Consistently use the phrase "This flag is available only in Enterprise binaries" across
  all the enterprise-specific command-line flags.

- Remove unneeded level of indirection for `noLicenseMessage` and `expiredMessage` string contants
  in order to improve code readability and maintainability.

- Remove unneded `return` statements after `logger.Fatalf()` calls, since these calls exit the app and never return.

- Make sure that the info log message about successful license verification is emitted
  when the license is verified successfully. Previously the error message could be logged
  when the license payload is invalid or if it misses some required features.

lib/promscrape: make concurrency control optional (#5073)
* lib/promscrape: make concurrency control optional

Before, `-maxConcurrentInserts` was limiting all calls to `promscrape.Parse`
function: during ingestion and scraping. This behavior is incorrect.
Cmd-line flag `-maxConcurrentInserts` should have effect onl on ingestion.

Since both pipelines use the same `promscrape.Parse` function, we extend it
to make concurrency limiter optional. So caller can decide whether concurrency
should be limited or not.

This commit makes c53b5788b4
obsolete.

Revert "lib/promscrape: add metric vm_promscrape_scrapes_skipped_total (#5074)"
This reverts commit 74301cdbf5.

Reason for revert:

vmagent already provides better approach for detecting slow scrape targets via the following query:

    scrape_duration_seconds / scrape_timeout_seconds > 1

This query depends on automatically generated per-target metrics.
See https://docs.victoriametrics.com/vmagent.html#automatically-generated-metrics for more details.
