dashboards: add Disk space usage % and Disk space usage % by type panels (#3436)
The new panels have been added to the vmstorage and drilldown rows.

`Disk space usage %` is supposed to show disk space usage percentage.
This panel is now also referred by `DiskRunsOutOfSpace` alerting rule.
This panel has Drilldown option to show absolute values.

`Disk space usage % by type` shows the relation between datapoints
and indexdb size. It supposed to help identify cases when indexdb
starts to take too much disk space.
This panel has Drilldown option to show absolute values.

vmalert: reduce allocations for Prometheus resp parse (#3435)
Method `metrics()` now pre-allocates slices for labels
and results from query responses. This reduces the number 
of allocations on the hot path for instant requests.

vmalert: fix replay step param (#3428)
The recent change in modifying default value
of `datasource.queryStep` flag resulted in situation
where replay mode was always running queries with
step=`datasource.queryStep`. When it should always
use rule's evaluation interval.

The fix is related not to replay mode only, but
for all Range requests. Now step param is set
individually for each mode.

lib/promscrape: optimize service discovery speed
- Return meta-labels for the discovered targets via promutils.Labels
  instead of map[string]string. This improves the speed of generating
  meta-labels for discovered targets by up to 5x.

- Remove memory allocations in hot paths during ScrapeWork generation.
  The ScrapeWork contains scrape settings for a single discovered target.
  This improves the service discovery speed by up to 2x.
