* 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`.

* 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.

- 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.
reduce lock contention for heavy aggregation requests
previously lock contetion may happen on machine with big number of CPU due to enabled string interning. sync.Map was a choke point for all aggregation requests.
Now instead of interning, new string is created. It may increase CPU and memory usage for some cases.

Strip sensitive information such as auth headers or passwords from datasource, remote-read,
remote-write or notifier URLs in log messages or UI. This behavior is by default and is controlled via
`-datasource.showURL`, `-remoteRead.showURL`, `remoteWrite.showURL` or `-notifier.showURL` cmd-line flags.

`median_over_time` is handled by predefined WITH template in MetricsQL library which translates it to `quantile_over_time(0.5)`
This makes it impossble to use `median_over_time` as a usual rollup function for `aggr_over_time`.

* vmagent: retry failed write request on the closed connection
Retry failed write request on the closed connection immediately,
without waiting for backoff. This should improve data delivery speed
and reduce amount of error logs emitted by vmagent when using idle connections.

* vmalert: correctly re-instantinate HTTP req on retries
Previosly, request retry to datasource re-used existing HTTP request.
But if request object was already partially processed (body was read),
then retry will be unsuccessful.
The change re-instantinates HTTP request object before retry.

- Fix Prometheus-compatible naming after applying the relabeling if -usePromCompatibleNaming command-line flag is set.
This should prevent from possible Prometheus-incompatible metric names and label names generated by the relabeling.
- Do not return anything from relabelCtx.appendExtraLabels() function, since it cannot change the number of time series
passed to it. Append labels for the passed time series in-place.
- Remove promrelabel.FinalizeLabels() call after adding extra labels to time series, since this call has been already
made at relabelCtx.applyRelabeling(). It is user's responsibility if he passes labels with double underscore prefixes
to -remoteWrite.label.

vmagent: properly add extra labels before sending data to remote storage
labels from `remoteWrite.label` are now added to sent metrics just before they
are pushed to `remoteWrite.url` after all relabelings, including stream aggregation relabelings (#4247)

This reverts commit 252643d100.
Reason for revert: the commit incorrectly fixes the the issue.
The `remoteAddr` must be properly quoted inside lib/httpserver.GetQuotedRemoteAddr().
It isn't quoted properly if the request contains X-Forwarded-For header.
The proper fix will be included in the follow-up commit.
