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.

aefba16d5e app/vmagent/remotewrite: expose vmagent_remotewrite_send_duration_seconds_total metric
This metric can be used for determining high saturation of every connection to remote storage with
an alerting query `rate(vmagent_remotewrite_send_duration_seconds_total) > 0.9s`.
This query triggers when a connection is satureated by more than 90%

Change default value of '-remoteWrite.queues' to cgroup.AvailableCPUs * 2 (#1385)
* Change default value of '-remoteWrite.queues' to cgroup.AvailableCPUS() * 2 to reduce scrape interval

Default value of vmagent option '-remotewrite.queues' is 4 and default
size of vmagent ScheudleUnmarshalWorkers is number of CPUs, when available
CPUs is much greater than 4, e.g 32, worker are competing push queues
which will increase scrape interval and may cause scrape timeout.

* Update README and flag description

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.

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.
