- 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.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4247
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.

{vmagent/remotewrite,vminsert/common}: fix dropInput and keepInput flags inconsistency
Sync behavior for dropInput and keepInput flags between single-node and vmagent.
Fix vmagent not respecting dropInput flag and reverse logic for keepInput.
The deferred call's arguments are evaluated immediately, but the function call is not executed until the surrounding function returns.

Value of `-dedup.minScrapeInterval` comand-line flag must be higher than `evaluation_interval` in order to make sure that only one sample on each evaluation will be left after deduplication.
Moreover, value of `-dedup.minScrapeInterval` must be a multiple of vmalert's `evaluation_interval` in order to make sure that samples will be aligned between deduplication window periods.
