lib/promscrape/discovery/consul: expose service tags in individual labels __meta_consul_tag_<tagname> 
This simplifies copying service tags to target labels with the following relabeling rule:

- action: labelmap
  regex: __meta_consul_tag_(.+)

lib/storage: search for TSIDs for the given metricIDs in the previous indexdb if they aren't found in the current indexdb 
The issue triggers after the indexdb rotation for time series, which stop receiving new samples.
This results in missing data for such time series in query responses.

This commit should address the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3502

The issue has been introduced in 2dd93449d8

lib/{mergeset,storage}: do not block small merges by pending big merges - assist with small merges instead 
Blocked small merges may result into big number of small parts, which, in turn,
may result in increased CPU and memory usage during queries, since queries need to inspect
all the existing small parts.

The issue has been introduced in 8189770c50

lib/bytesutil: cache results for all the input strings, which were passed during the last 5 minutes from FastStringMatcher.Match(), FastStringTransformer.Transform() and InternString() 
Previously only up to 100K results were cached.
This could result in sub-optimal performance when more than 100K unique strings were actually used.
For example, when the relabeling rule was applied to a million of unique Graphite metric names
like in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3466

This commit should reduce the long-term CPU usage for https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3466
after all the unique Graphite metrics are registered in the FastStringMatcher.Transform() cache.

It is expected that the number of unique strings, which are passed to FastStringMatcher.Match(),
FastStringTransformer.Transform() and to InternString() during the last 5 minutes,
is limited, so the function results fit memory. Otherwise OOM crash can occur.
This should be the case for typical production workloads.

all: add -inmemoryDataFlushInterval command-line flag for controlling the frequency of saving in-memory data to disk 
The main purpose of this command-line flag is to increase the lifetime of low-end flash storage
with the limited number of write operations it can perform. Such flash storage is usually
installed on Raspberry PI or similar appliances.

For example, `-inmemoryDataFlushInterval=1h` reduces the frequency of disk write operations
to up to once per hour if the ingested one-hour worth of data fits the limit for in-memory data.

The in-memory data is searchable in the same way as the data stored on disk.
VictoriaMetrics automatically flushes the in-memory data to disk on graceful shutdown via SIGINT signal.
The in-memory data is lost on unclean shutdown (hardware power loss, OOM crash, SIGKILL).

vmalert: fix replay step param (#3428) 
The recent change in modifying default value
of `datasource.queryStep` flag resulted in situation
where replay mode was always running queries with
step=`datasource.queryStep`. When it should always
use rule's evaluation interval.

The fix is related not to replay mode only, but
for all Range requests. Now step param is set
individually for each mode.

lib/promscrape: optimize service discovery speed 
- Return meta-labels for the discovered targets via promutils.Labels
  instead of map[string]string. This improves the speed of generating
  meta-labels for discovered targets by up to 5x.

- Remove memory allocations in hot paths during ScrapeWork generation.

lib/promscrape: properly add exported_ prefix to labels, which clash with target labels if honor_labels: true option isn't set. 
The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function.
The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_`
prefix to labels inside `labels` slice become invisible in the returned `dst` labels.

While at it, properly handle some corner cases:

- Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix.
- Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label.

app/vmalert/templates: properly escape all the special chars in quotesEscape function 
Previously the `quotesEscape` function was escaping only double quotes.
This wasn't enough, since the input string could contain other special chars,
which must be escaped when put inside JSON string. For example, carriage return and line feed chars (\n\r),
backslash char, etc. This led to the following issues, which were improperly fixed:

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/890 - this issue
  was "fixed" by introducing the `crlfEscape` function, which led to unnecessary
  complications in user templates, while not fixing various corner cases
  such as backslash chars in the input string.
  See 1de15ad490

- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 - this issue
  was "fixed" by urlencoding the whole string passed to -external.alert.source
  command-line flag. This led to invalid urls, which couldn't be parsed by Grafana.
  See 00c838353d
  and 4bd0244599

This commit properly encodes the input string passed to `quotesEscape`, so it can be safely embedded inside JSON strings.

This commit deprecates crlfEscape template function and adds the following new template functions:

- strvalue and stripDomain - these functions are supported by Prometheus, so they were added
  for compatibility purposes.
- jsonEscape and htmlEscape for converting the input string to valid quoted JSON string
  and for html-escaping the input string, so it could be safely embedded as a plaintext
  into html.

This commit also documents all supported template functions at https://docs.victoriametrics.com/vmalert.html#template-functions
The deprecated crlfEscape function isn't documented on purpose, since its usefulness is negative in general case.

Revert "vmalert: escape query params if external alert source defined (#3267)" 
This reverts commit 00c838353d.

Reason for revert: it incorrectly fixes the issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3139 .
Now `-external.alert.source=explore?orgId=1&left=...` is converted to the following invalid url, which cannot be handled by Grafana:

https://grafana.example.com/explore%3ForgId%3D1%26left%3D...

The next commit will contain the correct fix of the issue - the `quotesEscape` function must
properly escape the string, so it could be embedded into JSON string. This function must
properly escape \n\r chars too. In this case the `crlfEscape` function becomes unnecessary.
Actually, the next commit makes the `crlfEscape` function deprecated.

lib/storage: subsitute searchTSIDs functions with more lightweight searchMetricIDs function 
The searchTSIDs function was searching for metricIDs matching the the given tag filters
and then was locating the corresponding TSID entries for the found metricIDs.

The TSID entries aren't needed when searching for time series names (aka MetricName),
so this commit removes the uneeded TSID search from the implementation of /api/v1/series API.
This improves perfromance of /api/v1/series calls.

This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls,
since now these calls cache small metricIDs instead of big TSID entries
in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs)
without the need to compress the saved entries in order to save cache space.

This commit also removes concurrency limiter during searching for matching time series,
which was introduced in 8f16388428, since the concurrency
for all the read queries is already limited with -search.maxConcurrentRequests command-line flag.

lib/promscrape: allow specifying full target url in __address__ label 
Previously the `__address__` label could contain only `host:port` part of the target url,
while the scheme and metrics path were obtained from `__scheme__` and `__metrics_path__`
labels. Now it is possible to set the full url in `__address__` label.

This makes valid the following scrape config, which is frequently used by novice users:

scrape_configs:
- job_name: foo
  static_configs:
  - targets:
    - http://host1/metrics1
    - https://host2/metrics2

app/vmselect/promql: remove empty series before applying aggregate function 
Previously empty series (e.g. series with all NaN samples) were passed to aggregate functions.
Such series must be ingored by all the aggregate functions.
So it is better from consistency PoV filtering out empty series before applying aggregate functions.

app/vmselect: ignore empty series for limit_offset (#3178) 
* app/vmselect: ignore empty series for `limit_offset`

VictoriaMetrics doesn't return empty series (with all NaN values) to
the user. But such series are filtered after transform functions.
It means `limit_offset` will account for empty series as well.

For example, let's consider following data set:
```
time series:
foo{label="1"} NaN, NaN, NaN, NaN // empty series
foo{label="2"} 1, 2, 3, 4
foo{label="3"} 4, 3, 2, 1
```

When user requests all series for metric `foo` the empty series
will be filtered out:
```
/query=foo:
foo{label="v2"} 1, 2, 3, 4
foo{label="v3"} 4, 3, 2, 1
```

But `limit_offset(1, 1, foo)` is applied to original series, not filtered yet.
So it will return `foo{label="v2"}` (skips the first in list)
```
/query=limit_offset(1, 1, foo):
foo{label="v2"} 1, 2, 3, 4
```

Expected result would be to apply `limit_offset` to already filtered list,
so in result we receive `foo{label="v3"}`:
```
/query=limit_offset(1, 1, foo):
foo{label="v3"} 4, 3, 2, 1
```

The change does exactly that - filters empty series before applying `limit_offset`.

vmalert: set default value for datasource.queryStep to 5m (#3149) 
Change default value for command-line flag `datasource.queryStep` from `0s` to `5m`.
Param `step` is added by vmalert to every rule evaluation request sent to datasource.
Before this change, `step` was equal to group's evaluation interval by default.
Param `step` for instant queries defines how far VM can look back for the last written data point.
The change supposed to improve reliability of the rules evaluation when evaluation interval
is lower than scraping interval.

vmalert: always re-evaluate Annotations (#3119) 
* vmalert: always re-evaluate Annotations

Previously, Annotations were evaluated only:
1. On alert creating.
2. On alert's value change.

This is premature optimization. It was assumed that since annotations
could contain only text with alert's labels or value - there is no need
in spending resources to re-compile Annotations.

Later, template function `query` was added, which can execute
arbitrary queries and return different results on every evaluation.
So if it was used in annotations, it would be executed only on init
or value change.

Another case when optimization caused an issue - annotations hot reload.
In this case, annotations of the active alert won't change even if Rule's
annotations were changed.

This fix enables Annotations re-evaluation on each iteration to resolve
issues above. It would have some impact on performance, but it is unlikely
it will be noticeable.

docs/Release-Guide.md: require manual push of the created release tags to public Github 
The automated push of release tags to Github require specifying the remote repository name
when doing `git push <remote-repo-name> v1.xx.y`.
The remote repository name can differ in different environments,
so it cannot be put into Makefile rule.

TODO: create a Makefile rule, which generates standard remote names for public
and private repositories in Git, so `git push` for release tags could be automated then.

vmalert: set alert's source link to UI instead of JSON source (#2986) 
We switch default alert's source link to redirect user
to vmalert's UI instead of previous JSON object. While it breaks
compatibility, it also supposed to improve user's experience.
The old behavior can be achieved by updating `-external.alert.source`
command-line flag.

app/vmselect: follow-up after 63e0f16062 
* Explicitly store a pointer to UserReadableError in the error interface.
  Previously Go automatically converted the value to a pointer before storing in the error interface.

* Add Unwrap() method to UserReadableError, so it can be used transparently with the other code,
  which calls errors.Is() and errors.As().

* Document the change in docs/CHANGELOG.md

app/vmselect/netstorage: improve scalability of blocks processing on systems with multiple CPU cores 
Previously a single syncwg.WaitGroup was used for tracking the lifetime of processBlock callbacks
across all the per-vmstorage goroutines. This could be slow on systems with many CPU cores
because of inter-CPU synchronization overhead.

Use a separate per-vmstorage sync.WaitGroup instead in order to reduce inter-CPU synchronization overhead.
This should imrpove performance for heavy queries over big number of blocks on multi-CPU systems.

lib/storage: prevent excessive loops when storage is in RO (#2962) 
* lib/storage: prevent excessive loops when storage is in RO

Returning nil error when storage is in RO mode results
into excessive loops and function calls which could
result into CPU exhaustion. Returning an err instead
will trigger delays in the for loop and save some resources.

Since the minimum supported Go version for VictoriaMetrics is Go1.17,

Deprecate alert's status link `/api/v1/<groupID>/<alertID>/status` in favour of

The change was needed for simplifying logic in vmselect for proxying vmalert's requests.

The old alert's status link will be still supported for a few versions but will be removed in the future.

Previously the time series could be put into dateMetricIDCache without
registering in the per-day inverted index if GetOrCreateTSIDByName

series in query results.

lib/storage: return marshaled metric names from SearchMetricNames 
Previously SearchMetricNames was returning unmarshaled metric names.
This wasn't great for vmstorage, which should spend additional CPU time
for marshaling the metric names before sending them to vmselect.

While at it, remove possible duplicate metric names, which could occur when
multiple samples for new time series are ingested via concurrent requests.

Also sort the metric names before returning them to the client.
This simplifies debugging of the returned metric names across repeated requests to /api/v1/series

all: limit the maximum memory usage for regexp cache, which stores parsed regular expressions in MetricsQL queries 
Previously the cache could store 10K unique regexps. When every regexp is huge (e.g. hundreds of kilobytes),
then the total cache size could grow to multiples of gigabytes. Now the cache size is limited by the total length
of all cached regexps. So huge regexps won't result in high memory usage for the cache.

lib/netutil.ConnPool: skip dialing remote address if the previous dial attempt was unsuccessful 
If the previous dial attempt was unsuccessful, then all the new dial attempts are skipped
until the background goroutine determines that the given address can be successfully dialed.

This reduces query latency when some of vmstorage nodes are unavailable and dialing them is slow.

This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/711

This commit is based on ideas from the https://github.com/VictoriaMetrics/VictoriaMetrics/pull/2756

The main differences are:

- The check for healthy/unhealthy storage nodes is moved one level lower from app/vmselect/netstorage to lib/netutil.ConnPool.
  This makes possible re-using this feature everywhere lib/netutil.ConnPool is used.
- The check doesn't take into account handshake errors for already established connections.
  Handshake errors usually mean improperly configured VictoriaMetrics cluster, so they shouldn't be ignored.

vmselect: limit end param max value by 2d in future (#2729) 
* vmselect: limit `end` param max value by 2d in future

The change is applied only to service handlers like `/labels` or `/series`
and limits the `end` param by max value <= now() + 2 days. The same limit
is applied for the ingested data, so no reason to allow to request data
in future far than that.

The change is also needed for corner cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2669
where too high `end` value triggers inefficient global index search.

docs/guides/migrate-from-influx.md: suggest more real-world value for -search.maxStalenessInterval 
Suggest `-search.maxStalenessInterval=10s` instead of `-search.maxStalenessInterval=1ms`,
since `1ms` would result in empty graphs in most cases, since the interval between data points
on the graph is usually much higher than 1ms. For example, if the graph shows time range of one hour
and it contains 1000 points, then the interval between points on the graph would equal to
3600s/1000=3.6 seconds.
