docs/Troubleshooting.md: document an additional case, which could result in slow inserts
If `-cacheExpireDuration` is lower than the interval between ingested samples for the same time series,
then vm_slow_row_inserts_total` metric is increased.

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.

It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

dashboards: add Disk space usage % and Disk space usage % by type panels (#3436)
The new panels have been added to the vmstorage and drilldown rows.

`Disk space usage %` is supposed to show disk space usage percentage.
This panel is now also referred by `DiskRunsOutOfSpace` alerting rule.
This panel has Drilldown option to show absolute values.

`Disk space usage % by type` shows the relation between datapoints
and indexdb size. It supposed to help identify cases when indexdb
starts to take too much disk space.
This panel has Drilldown option to show absolute values.

dashboards: cluster dashboard update (#3380)
The purpose of the update is to make the dash more usable
for large installations with many instances. Panels which showed
metrics per-instance (Mem, CPU) now are showing metrics per-job or min/max/avg
aggregations in % instead. This supposed to help immediately to identify
resource shortage and remain usable for small and big installations.

For cases when detailed info is needed, to the bottom of the dashboard
a new row `Drilldown` was added. Panels like Mem or CPU now contain
a `data-link` named `Drilldown` (cis shown on line click) which takes
user to more detailed panel.

The change list is the following:
* bump Grafana version to 9.1.0;
* replace old "Graph" panel with "TimeSeries" panel;
* improve Uptime panel to show number of instances per job;
* show % usage of Mem and CPU instead of absolute values;
* `Caches` row was removed. All needed info for caches is now part of `Troubleshooting`;
* add `Drilldown` section for detailed resource usage;
* 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-cluster.yml` change.
