Subject: [PATCH] dashboards: update VM single dash (#3400)

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.
