After further consideration and working with the feature for a few
weeks, the `configOverride` functionality seems to be more complexity
than is worth it for the expected benefit. Users still have the most
preferred option of setting configs in Ceph's config database using
`ceph cofig set` or the dashboard, and the override ConfigMap still
exists for fallback scenarios. The config database can still be used
by Rook for setting necessary configs, but the user has no way of
telling Rook to do so.
