Version below 2.22 rate graphs fail due to [1]. 1. grafana/grafana#71052
Before this patch, older Grafana 6 color scheme were used for overview panel. It was fine for Grafana from 8 to 10, but don't work properly with Grafana 11. After this patch, the panel works properly with Grafana 11 and newer. For Grafana 9 and 10 everything works fine, except for row coloring: only single cell is colored [1]. For Grafana 8 and older, table column hiding no longer works properly so it's simpler for us to treat it as unsupported since it's EOLed 1 year and 3 months ago [2]. 1. grafana/grafana#27542 2. https://endoflife.date/grafana Follows #234

dashboard: fix cluster overview for Grafana 11
grafonnet doesn't fill up empty thresholds for hidden fields. After table code rework introduced in Grafana 11, empty thresholds result in panel crush.
Thanks to @0x501D for exploring the issue.
Closes #234
dashboard: use Grafana 11 color scheme in overview table
Before this patch, older Grafana 6 color scheme were used for overview panel. It was fine for Grafana from 8 to 10, but don't work properly with Grafana 11 [Figure 1]. After this patch, the panel works properly with Grafana 11 and newer [Figure 2]. For Grafana 9 and 10 everything works fine, except for row coloring: only single cell is colored [1, Figure 3]. For Grafana 8 and older, table column hiding no longer works properly so it's simpler for us to treat it as unsupported since it's EOLed 1 year and 3 months ago [2, Figure 4].
