Y-min set to 0 gives better understanding of changes, as it shows absolute change.
Otherwise, the panel will show relative change and could make a false impression
of the changes.
Other panels in dashboards are either instant (no historical data displayed),
or already set to Y-min: 0.

This should improve precision of `restarts` and `version change` annotations when
zooming-in/zooming-out on the dashboards.
The change also makes `restarts` dashboard visible on the panels, so user can disable it from
displaying if needed. This could be useful when restarts overlap with version change events.

The error appears when executing annotations query against Prometheus backend
because the query itself hasn't specified look-behind window (which is allowed
in VictoriaMetrics query engine).

and advice users on how this can be addressed.

The panel `Errors rate to Alertmanager` had `group` label filter
applied to the expression, while the metric `vmalert_alerts_send_errors_total`
doesn't have that label. This resulted into always empty results.

* dashboards/*: add `restarts` annotation to show when there were restarts
The cluster's annotation query is aggregated `by job`,
while vmagent/vmalert are aggregated `by job, instance`.
This is because cluster dashboard can contains too many instances
and annotation could become too noisy.

Got "Failed to upgrade legacy queries Datasource $ds was not found" in
Grafana on operator dashboard.
It's datasource variable was incorrectly named `datasource`.
Also made the rest of the dashboards have homogeneous datasource-variable
names and selections, matching vmagent dashboard.
The new annotation is hidden by default and suppose to show
component `short_version` label change on the panels.
