cdc372bb98 app/vmselect: add -search.noStaleMarkers command-line flag for disabling stale markers handling in queries 
This option allows reducing CPU usage a bit when VictoriaMetrics is used
for collecting and processing non-Prometheus data. For example, InfluxDB line protocol, Graphite, OpenTSDB, CSV, etc.

226143f31b lib/promscrape: add ability to disable sending Prometheus staleness markers with -promscrape.disableStaleMarkers command-line flag 
This option can be useful when vmagent consumes too much additional memory
for staleness markers functionality and when staleness markers aren't needed.

8f973e34fb lib/workingsetcache: properly switch to whole mode 
Previously the switch from `split` to `whole` mode had been performed too early,
e.g. when the current cache size became bigger than 1/4 of the allowed cache size.

Now it is performed when the current cache size becomes bigger than 1/2 of the allowed cache size.

This change can reduce memory usage for data ingestion path when big number of active time series are ingested.

84fb59b0ba lib/storage: move deletedMetricIDs set from indexDB to Storage 
This makes consitent the list of deleted metricIDs when it is used from both the current indexDB and the previous indexDB (aka extDB).
This should fix the issue, which could lead to storing new samples under deleted metricIDs after indexDB rotation.
See more details at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1347#issuecomment-861232136 .

Thanks to @tangqipengleoo for the initial analysis and the pull request - https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

This commit resolves the issue in more generic way compared to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/1383 .

The downside of the commit is the deletedMetricIDs set isn't cleaned from the metricIDs outside the retention. It needs app restart.
This should be OK in most cases.

ce9e163e94 lib/httpserver: stop the process on panics in request handlers 
Panics may leave the process in inconsistent state. That's why it is better to stop the process after the panic
instead of recovering from the panic. Unfortunately, the standard net/http.Server recovers panics in request handlers.
See https://github.com/golang/go/issues/16542 . That's lib/httpserver must stop the process on itself after the panic.

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.

f010d773d6 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.

904dababcc 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.

Previously vmagent was creating a separate Kubernetes object cache per each scrape job.
This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.)
as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113

Now it uses a shared map of scrape objects across multiple scrape jobs.

This should prevent from holding previously discovered []ScrapeWork slices when a part of discovered targets changes over time.

Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.

994fa2f3bf app/vmselect/promql: add buckets_limit(k, buckets) function, which limits the number of buckets per time series to k 
This function works with both Prometheus-style and VictoriaMetrics-style buckets.
The function removes buckets with the lowest values in order to reserve the highest precision.
The function is useful for building heatmaps in Grafana from too big number of buckets.

6daa5f7500 lib/storage: prioritize data ingestion over heavy queries 
Heavy queries could result in the lack of CPU resources for processing the current data ingestion stream.
Prevent this by delaying queries' execution until free resources are available for data ingestion.

Expose `vm_search_delays_total` metric, which may be used in for alerting when there is no enough CPU resources
for data ingestion and/or for executing heavy queries.
