With parent task done and once there's enough data accumulated in Promethes (e.g. 10/12 weeks) we can deprecate the `cachestats` varnish python subsystem. The following daemons will need to be removed:
[x] varnishmedia
[] varnishreqstats
[x] varnishrls
[] varnishstatsd
[x] varnishxcache
[x] varnishxcps
== varnishstatsd
The following dashboards have varnishstatsd Graphite metrics (i.e. `varnish\..*\.backends\..*`)
[] db/api-frontend-summary (API frontend summary)
The Prometheus version is at https://grafana.wikimedia.org/d/Dueegx4Zz/api-frontend-summary-filippo-t184942 although the "rest api varnish hit rate %" for varnish vs restbase metric can't be converted yet because we'd need to calculate over metrics from two different data sources: restbase GET/s (graphite) and varnish restbase backend GET/s (prometheus)
[x] db/experimental-backend-5xx (Experimental - backend 5xx)
Scheduled to be deleted, unused
[] db/maps-performances (Maps performances)
Prometheus version at https://grafana.wikimedia.org/d/kcAMMw4Wk/maps-performances-filippo-t184942
[x] db/media (Media)
Fixed
[] db/wdqs-paper-data (WDQS Paper data)
Needs updating (?)
[] db/wikidata-query-service-frontend (Wikidata Query Service Frontend)
Needs updating (?)
