8e7d1f8824 app/vmagent/remotewrite: use WARN level instead of ERROR level for couldnt send a block with size ... bytes to ... log message 
This is really warning, since vmagent re-tries sending the data block until success.

52b4b1605e app/vmagent/remotewrite: increase the maximum possible number of inmemory blocks for systems with high amounts of RAM 
This should reduce the probability of using much slower file-based persistent queue
when vmagent processes metrics at high rate (millions of metrics per second).

fb37b853e9 app/vmagent/remotewrite: count maxLabelsPerBlock as 10x of maxRowsPerBlock 
This should increase block sizes and subsequently increase the maximum possible bandwidth per each connection to remote storage.
This, in turn, should reduce the probability of storing the data in local buffers.

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.

71ea4935de lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors 
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.
