The new metric `vmagent_remotewrite_queues` exports a static value of
number of configured remote write queus. This metric is useful to
calculate total saturation per each configured URL with given number
of queues. See corresponding changes to vmagent alerts and dashboard.

* dashboards: remove index filter from stats panel for DiskUsage
The diskUsage stats panel was showing disk usage without including
size of the index, which is not correct. The filter was removed
to reflect the total disk usage.

* dashboards: replace fixed interval of `5m` for `rate` expressions
Before we used fixed `5m` interval for expressions with `rate` func.
Unfortunately, this interval wasn't a fit for all the cases. So we
switch to `$__rate_interval` instead.

imported. It was also integrated into docker-compose environment.
