refactor!: removes the grafana operator

* refactor!: removes the grafana operator

BREAKING CHANGE: after contacting key users, they expressed that MSO deploying
the grafana operator was not interesing for them, thus we have deciced
to remove the grafana operator completely.
Issue: https://issues.redhat.com/browse/MON-2247

This PR also removes ability for MSO to create GrafanaDataSource

BREAKING CHANGE: since we removed the grafana operator from MSO, it
also does not make sense for MSO to manage a GrafanaDataSource
