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.

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.

* app/vmalert: add `remoteWrite.sendTimeout` command-line flag to configure timeout for sending data to `remoteWrite.url`
* vmalert: remove WriteTimeout from clients Cfg
No need to have it as a part of configuration struct:
* the client isn't used by other packages;
* there are no internal tests to check the WriteTimeout.
* vmalert: remove DisablePathAppend from clients Cfg

- 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.
The change list is the following:
* bump Grafana version to 9.2.6;
* replace old "Graph" panel with "TimeSeries" panel;
* show % usage of Mem and CPU additionally to of absolute values;
* `Caches` row was removed. All needed info for caches is now part of `Troubleshooting`;
* add Annotations for Alert triggers. Not all alerts are supposed to be displayed
on the dashboard, but only those with label `show_at: dashboard`.
See `alerts.yml` change.
