- Return immediately on context cancel during the backoff sleep.
This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3747
- Add a comment describing why the second attempt to obtain the response from remote side
is perfromed immediately after the first attempt.
- Remove fasthttp dependency from lib/promscrape/discoveryutils
- Set context deadline before calling doRequestWithPossibleRetry().
This simplifies the doRequestWithPossibleRetry() a bit.

* 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
* feat: include fonts in the build
