1088113110 lib/uint64set: remove memory allocation in getOrCreateSmallPool()
This partially reverts fb82c4b9fa

It has been appeared that the additional memory allocation may result in higher GC pauses.
It is better to spend CPU time on copying bigger bucket16 structs instead of increasing query latencies due to higher GC pauses

alerts: make alerting rule RPCErrors compatible with PromQL (#1204)
Original query can't be executed via PromQL which results in error
if expression is evaluated by Prometheus. The new expression is
compatible with both engines.

19906dc30e Allow specifying build date from a variable (#1200)
Just like the existing infrastructure for `BUILDINFO_TAG`, this can ease the production of [reproducible builds](https://wiki.freebsd.org/ReproducibleBuilds).
(e.g. in FreeBSD the date the port was committed is used at build time, not the actual build time, so that an identical port produced at different times produces an identical executable)

ff3711eea2 docs: update docs ordering and formatting (#1192)
The major change is adding `sort` directive to docs. For those docs which are copied
from internal packages `sort` is added via makefile command. For the rest it is added
manually since they're updated manually as well.

The rest of changes is connected with markdown formatting. For example, changing headers
in some files (`##` => `#`) makes navigation on .github.io to look better. This especially
useful for `changelog` docs.

Table of contents for `vmctl` is dropped, since we already have it autogenerated on .github.io.

No link changes expected. The corresponding PR to `cluster` branch will be made in follow-up PR.

9da2ef3d8f lib/promscrape/discovery/kubernetes: load objects missing in local cache from api seriver in getObjectByRole()
This should fix possible race for `role: endpoints` and `role: endpointslices` service discovery,
when the referred `pod` and `service` objects aren't propagated to urlWatcher cache yet.

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1182#issuecomment-813353359 for details.

fe084fdd33 lib/promscrape/discovery/kubernetes: synchronously load Kubernetes objects on first access
Remove async registration of apiWatchers, since it breaks discovering `role: endpoints` and `role: endpointslices` targets,
which depend on pod and service objects.

There is no need in reloading `endpoints` and `endpointslices` targets if the referenced `pod` or `service` objects change,
since in this case the corresponding `endpoints` and `endpointslices` objects should also change because they contain
ResourceVersion of the referenced `pod` or `service` objects, which is modified on object update.
