While at it, stop sending requests to unavailable backend for 3 seconds
before the next attempt. This should reduce the amounts of useless work
and the number of useless network packets when the backend is temporarily unavailable.
* app/vmauth: add concurent requests limit per auth record
* app/vmauth: added clarification comment
* app/vmauth: remove unused code
* app/vmauth: move read from limiter
* app/vmauth: fix text
* app/vmauth: fix comments
* - Clarify the docs for the max_concurrent_requests option at docs/vmauth.md
- Clarify the description of the change at docs/CHANGELOG.md
- Make sure that the -maxConcurrentRequests takes precedence over per-user max_concurrent_requests
- Update tests for verifying that the max_concurrent_requests option is parsed properly

- Document the change at docs/CHANGELOG.md
- Add `Reading rules from object storage` section to docs/vmalert.md
- Add `s3` prefix to command-line flags related to the configuration of s3 and gcs clients
- Explicitly mention that reading rules from object storage is supported only in enterprise version
* vmalert: support object storage for rules
Support loading of alerting and recording rules from object
storages `gcs://`, `gs://`, `s3://`.
* review fixes
* vmalert: use group's ID in UI to avoid collisions
Identical group names are allowed. So we should used IDs
for various groupings and aggregations in UI.

* vmalert: exclude `updates` field from json marhsaling
This field isn't correctly marshaled right now.
And implementing the correct marshaling for it doesn't
seem right, since json representation is mostly used
by systems like Grafana. And Grafana doesn't expect this
field to be present.

* vmalert: speed up state restore procedure on start
Alerts state restore procedure has been changed to become asynchronous.
It doesn't block groups start anymore which significantly improves vmalert's startup time.
Instead, state restore is called by each group in their goroutines after the first rules
evaluation.
While previously state restore attempt was made for all loaded alerting rules,
now it is called only for alerts which became active after the first evaluation.
This reduces the amount of API calls to the configured remote read URL.
This also means that `remoteRead.ignoreRestoreErrors` command-line flag becomes deprecated now
and will have no effect if configured.

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

* fix: reduce size fonts

- 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.
