Using metric `vm_concurrent_queries` in relation to `vm_concurrent_select_capacity`
is incorrect. Switching to `vm_concurrent_select_current` in `Concurrent selects` panel.

Before we used fixed `5m` interval for expressions with `rate` func.
Unfortunately, this interval wasn't a fit for all the cases. So we
switch to `$__rate_interval` instead.

caused by churn rate or new series registration.

The diskUsage stats panel was showing disk usage without including
size of the index, which is not correct. The filter was removed
to reflect the total disk usage.

* 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.

It should help to determine underutilized types of caches.

* rm cumulative visualisation for panel `Disk space used`.
It uses % threshold and cumulative display breaks it.
* remove area filling for resource usage row;
* add job name for panels in resource usage row.
* dashboard: update vmagent dash
The update contains the following changes:
* display anonymous memory usage metric. This metric suppose to reflect
memory usage of the process which can't be freed by OS;
* add legends to all panels. This is important for cases when users share
the screenshots;
* modify panels for Grafana v8.0.0
* dashboard: update cluster dash
The update contains the following changes:
* move stats panels to Configuration row, so it can be collapsed;

* dashboard: disable area fill for Cache hit ratio
* dashboard: minor display updates
* dashboard: add panel `Concurrent flushes on disk`
* dashboard: add `Rows ignored` panel
* dashboard: update ChurnRate panel with proper description and additional query over 24h time window
* add panel `Open FDs` for file descriptors metrics;
* add panel `Disk writes/reads` to show the real read/write
load on storage layer;
* add stats panel to show available CPUs, memory and disk space.
* Slow metrics load panel was removed since it is hard to interpret without
additional metrics and stats;
* Slow inserts panel was updated to display percentage of slow inserts comparing
to total number of inserts to show the real impact.
* The new update introduces new row "Troubleshooting" that
contains panels for churn rate and slow-queries/inserts/loads metrics. This row supposed to be reveal the cause of low performance or other issues;
* CPU panel got `short` units instead of `seconds`;
* Overview row was updated with panel showing bytes-per-datapoint stat;
* Overview row was updated with panel showing free disk space.
The list of changes is following:
* fix Uptime panel column styles according to changes introduced in 6.7 Grafana version
* fix panel `vminsert/Rows per insert` due to metric rename - see #336
* change default datasource to VictoriaMetrics since dashboard now uses MetricsQL for `vminsert/Rows per insert` panel
