This allows better controlling requests to backends and providing better error logging.
For example, if the backend was unavailable, then the ReverseProxy was logging the error
message without client ip and the initial request uri. This could harden debugging.
This is based on https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3486
The docs/assets folder should be used only for assets specific to docs generation at https://docs.victoriametrics.com, e.g. css, js and images.
All the other assets related to specific docs should be placed in the same folder as the corresponding *.md file.
These assets should have the same name prefix as the corresponding doc file name. This simplifies tracking the lifetime of these assets.
For example, if the doc is removed, it is very easy to remove all assets associated with it with a simple `rm -rf docs/doc-name*` command.
This also simplifies generating correct urls for doc-specific assets from both https://docs.victoriametrics.com
and from https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/docs/ - just refer to the asset name without any directory prefixes.

Switch to the actual API version `2016-11-15`,
since the old version doesn't provide access to all
the fields which implementation expects.
For example, old API missing `zone_id` field
in `DescribeAvailabilityZonesResponse` response.

Allow users fine-tuning the maximum string length for interning via -internStringMaxLen command-line flag.
This may be used for fine-tuning RAM vs CPU usage for certain workloads.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3692
- Call httpserver.GetQuotedRemoteAddr() and httpserver.GetRequestURI() only when the error occurs.
This saves CPU time on fast path when there are no parsing errors.
- Create a helper function - httpserver.LogError() - for logging the error with the request uri and remote addr context.
Stale series are sent when there is a difference between current
and previous scrapes. Those series which disappeared in the current scrape
are marked as stale and sent to the remote storage.
Sending stale series requires memory allocation and in case when too many
series disappear in the same it could result in noticeable memory spike.
For example, re-deploy of a big fleet of service can result into
excessive memory usage for vmagent, because all the series with old
pod name will be marked as stale and sent to the remote write storage.
This change limits the number of stale series which can be sent at once,
so memory usage remains steady.
