`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`.

* expose metrics `vmauth_config_last_reload_*` for tracking the state of config reloads, similarly to vmagent/vmalert components.
* do not print logs like `SIGHUP received...` once per configured `-configCheckInterval` cmd-line flag. This log will be printed only if config reload was invoked manually.
* prevent configuration reloading if there were no changes in config. This improves memory usage when `-configCheckInterval` cmd-line flag is configured and config has extensive list of regexp expressions requiring additional memory on parsing.

- Switch from summary to histogram for vl_http_request_duration_seconds metric.
This allows calculating request duration quantiles across multiple hosts
via histogram_quantile(0.99, sum(vl_http_request_duration_seconds_bucket) by (vmrange)).
- Take into account only successfully processed data ingestion requests
when updating vl_http_request_duration_seconds histogram.
Failed requests are ignored, since they may significantly skew measurements.
- Clarify the description of the change at docs/VictoriaLogs/CHANGELOG.md.

Adding limit on ingestion allows to avoid issues like this one https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762
Such issues are often caused by misconfigurtion on log persing/ingestion side and preventing such rows from being ingested allows to avoid performance implications created by storing such log rows.

Adds `eval_offset` attribute for Groups.
If specified, Group will be evaluated at the exact time offset on the range of [0...evaluationInterval].
The setting might be useful for cron-like rules which must be evaluated at specific moments of time.

* app/vminsert: properly close vmstorage connection
previously vmstorage may stuck in broken state until vminsert restarts
since vmstorage was marked as read-only and connection was broken to it.
checkReadonly function never marked connection as broken

* app/vminsert: fixes readonly check
previously vminsert doesn't check readOnly state for vmstorage, since check was never performed for nil buffer
In this case every 30 second storage node loss readonly state and received some data.
It caused re-routing and possible slow down for ingestion

Disallow parsing multitenant token at auth.NewToken().
Use auth.NewTokenPossibleMultitenant() at vminsert only. All the other callers should call auth.NewToken(),
since they do not support multitenant token.
This is a follow-up for f0c06b428e
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4910
Remove extra error message when auth token is nil. The default message
about unsupported path should be more clear to the user who mistakenly
requested /multitenant path.
