* 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.

* lib/storage/partition: add check to ensure parts exist on disk
If part exists in parts.json but is missing on disk there will be a misleading error similar to "unexpected number of substrings in the part name".
This change forces verification of part existence and throws a correct error in case it is missing on disk.
Such issue can be result of https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5005 or disk corruption.

- 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.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4934
- Move the bugfix description to the correct place in docs/CHANGELOG.md
- Prevent from logging of 'context canceled' errors after the url watcher is stopped,
since these errors are expected and may confuse users.
- Remove unused urlWatcher.refCount field.
- Remove unused urlWatcher.close() method.

* lib/promscrape/discovery/kubernetes: fix leaking api watcher
goroutine which was polling k8s API had no execution control. This leaded to leaking goroutines during config reload.

* lib/promscrape/discovery/kubernetes: remove waitgroup sync for goroutines polling API server
This is unnecessary since context will is cancelled and new requests will not be sent. Also, using waitgroup will increase time required to perform reload which might result in missed scrapes.

* lib/backup: force copying of parts.json
Copying of parts.json is required because `part.key()` comparison can create same key value for files with different contents. This will result in inconsistent backup being created or restored.

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.

This automation doesn't work as intended on LTS releases, bugfix releases and custom releases,
since it assumes every new tag is related only to new release.
Also the github.com/VictoriaMetrics/ops repository may contain manually set custom tags
for VictoriaMetrics components (for example, for testing the latest bugfixes or features),
which are overwritten by the generated pull request.
The way to go is to manually update tags at github.com/VictoriaMetrics/ops repository when needed
instead of trying to automate this process.
This should prevent from emitting too long lines when too long args are passed to logger.* functions.
For example, too long MetricsQL queries or too long data samples.
