Roman Khavronenko 34d190b32a dashboards: add dashboard for exploring stored metrics (#10617)
The new Grafana dashboard uses the following APIs:
- /api/v1/status/tsdb
- /api/v1/status/metric_names_stats

It shows the list of metric names, the request count and the last time
they were "used". Clicking on metric name allows exploring its
cardinality.

Based on https://github.com/VictoriaMetrics/VictoriaMetrics/issues/9832

The PR contains a few unrelated changes: 
* rename of folder for prometheus datasource to remove the duplicated
word
* fix for vmalert's access to the datasource, as before it wasn't able
to write/read properly

-------------

The dashboard screen cast:
