Update wording to highlight that cache is not persistent if flag is
value is empty. Previously, it was not clear if cache is not used at all
or just not persistent.
* It must reduce memory usage for misbehaving clients. Since
VictoriaMetrics stores sparse index inmemory.
* Reduce disk space usage for indexdb.
* Prevent possible indexDB items drops.
* It may trigger slow insert and new timeseries registration due to
default value for flag change

This PR fixes an issue where parsing long `_msg` values caused errors,
resulting in some log records not being displayed.
The error occurred due to partial processing of strings. In some cases,
a long record could be split into multiple chunks, causing only part of
the record to be processed instead of the entire entry.

This should improve precision of `restarts` and `version change` annotations when
zooming-in/zooming-out on the dashboards.
The change also makes `restarts` dashboard visible on the panels, so user can disable it from
displaying if needed. This could be useful when restarts overlap with version change events.

Occasionally, vmagent sends empty blocks to downstream servers. If a
downstream server returns an unexpected response, vmagent gets stuck in
a retry loop. While vmagent handles 400 and 409 errors, there are
various prometheus remote write implementations that return different
error codes. For example, vector returns a 422 error. To mitigate the
risk of vmagent getting stuck in a retry loop, it is advisable to skip
sending empty blocks to downstream servers.

* adds datadog extensions for statsd:
- multiple packed values (v1.1)
- additional types distribution, histogram
* adds type check and append metric type to the labels with special tag
name `__statsd_metric_type__`. It simplifies streaming aggregation
config.
* remove statsd support from cluster, since cluster doesn't support
stream aggregation.

(cherry picked from commit 6b493582da)
The new flag type is supposed to be used for specifying URL values which
could contain sensitive information such as auth tokens in GET params or
HTTP basic authentication.
The URL flag also allows loading its value from files if `file://`
prefix is specified. As example, the new flag type was used in
app/vmbackup as it requires specifying `authKey` param for making the
snapshot.
