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.

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.

93a318d1bf vendor: update github.com/VictoriaMetrics/metrics from v1.15.3 to v1.16.0
This adds the following new metrics for each VictoriaMetrics app:

* process_resident_memory_anonymous_bytes - the RSS share for memory allocated by the process itself.
  This share cannot be freed by the OS, so it must be taken into account by OOM killer.

* process_resident_memory_pagecache_bytes - the RSS share for page cache memory (aka memory-mapped files).
  This share can be freed by the OS at any time, so it must be ignored by OOM killer.
