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.

(cherry picked from commit 683f8c2780)
`vmalert_iteration_total` series number is 4 time less than
`vmalert_iteration_duration_seconds`, queries will be lighter.
(cherry picked from commit 75ad6c1b49)
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.

(cherry picked from commit 9dd9b4442f)
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).

It should help identifying cases when too much CPU is spent on garbage collection,
and advice users on how this can be addressed.

The new panel supposed to indicate alerting groups that miss their evaluations.

(cherry picked from commit aaf9e3d526)
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.

* dashboards: add `CPU percentage` panel for cluster dashboards
The new panel `CPU percentage` was added instead if adding a limit
to the existing `CPU` panel because dasbhoard may display big number
of components each with own limits. The separate panel should provide
a clear display of CPU load.
