app/vmselect: expose vm_memory_intensive_queries_total counter metric (#5208)
The new metric gets increased each time `-search.logQueryMemoryUsage` memory limit
is exceeded by a query. This metric should help to identify expensive and heavy queries
without inspecting the logs.

lib/httpserver: add flags to specify HSTS / Frame-Options / CSP headers for httpserver (#5111)
support `Strict-Transport-Security`, `Content-Security-Policy` and `X-Frame-Options`
HTTP headers in all VictoriaMetrics components. 
The values for headers can be specified by users via the following flags: 
`-http.header.hsts`, `-http.header.csp` and `-http.header.frameOptions`.

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.

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/*

docs/Single-server-VictoriaMetrics.md: add a link to the original issue, which describes how to run VictoriaMetrics as Windows service
This is a follow-up for cc7d5b7bab

The original issue https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3781 contains
up-to-date information on how to run VictoriaMetrics components as Windows service,
plus it may contain additional information about this case such as https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3781#issuecomment-1708092680 ,
so it is better to refer this issue from the docs.

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.

flagutil: Make .Msecs private (#4906)
* Introduce flagutil.Duration

To avoid conversion bugs

* Fix tests

* Clarify documentation re. month=31 days

* Add fasttime.UnixTime() to obtain time.Time

The goal is to refactor out the last usage of `.Msecs`.

* Use fasttime for time.Now()

* wip

- Remove fasttime.UnixTime(), since it doesn't improve code readability and maintainability
- Run `make docs-sync` for syncing changes from README.md to docs/ folder
- Make lib/flagutil.Duration.Msec private
- Rename msecsPerMonth const to msecsPer31Days in order to be consistent with retention31Days

- Remove support for JSON parsing, since it is too fragile and is rarely used in practice.

  The JSON parser can be added in the future if needed.
- Remove unused code from lib/protoparser/opentelemetry/pb and lib/protoparser/opentelemetry/proto
- Do not re-use protobuf message between ParseStream() calls, since there is high chance
  of high fragmentation of the re-used message because of too complex nested structure of the message.

lib/streamaggr: follow-up for 736197179e
- Use a byte slice instead of a map for tracking indexes for matching series.
  This improves performance, since access by slice index is faster than access by map key.
- Re-use the byte slice for tracking indexes for matching series.
  This removes unnecessary memory allocations and improves stream aggregation performance a bit.
- Add an ability to return to the previous behvaiour by specifying -remoteWrite.streamAggr.dropInput command-line flag.
  In this case all the input samples are dropped when stream aggregation is enabled.
- Backport the new stream aggregation behaviour from vmagent to single-node VictoriaMetrics when -streamAggr.config
  option is set.
- Improve docs regarding this change at docs/CHANGELOG.md
- Document the new behavior at docs/stream-aggregation.md
