vmctl: properly convert influx bools into integer representation
When using vmctl influx, the import would fail importing boolean fields
with:
```
failed to convert value "some".0 to float64: unexpected value type true
```
This converts `true` to `1` and `false` to `0`.
Fixes#1709
The purpose of update is to make README and flags description more
clear to the reader. Especially, show that vm-account-id flag is required
for clustered version of VM.
The `::tag` type is needed in cases when field and tag names are equal, which
results into unexpected results in InfluxQL. Setting the type explicitly helps
InfluxDB to understand which exact column we apply filter to.

* docs: drop table of contents for `vmctl`
We already have it autogenerated on .github.io, so no need to keep it.
* docs: mention OpenTSDB migration feature for vmctl
* docs: sync docs for `vmalert`
* add more documentation on OpenTSDB migration explaining what chunking means
* more clarification of OpenTSDB aggregations
* break out what a retention string becomes
* add more docs around retention strings
* add example of running program and fix mistake in how hard offsets are handled
* fix formatting
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.
The archive contains the following executables for Windows:
* vmagent
* vmalert
* vmauth
* vmctl
Other components - vmbackup, vmrestore, victoria-metrics - aren't supported for Windows yet
It is better developing vmctl tool in VictoriaMetrics repository, so it could be released
together with the rest of vmutils tools such as vmalert, vmagent, vmbackup, vmrestore and vmauth.
