Allow users to specify overrides in the CephCluster CRD. The override ConfigMap still exists for emergency situations and is mounted into daemon pods directly instead of being merged into a Rook-created config file. Rook Ceph no longer uses a config file for managing daemons with the exception of the OSDs which still generate a config in an init container. Signed-off-by: Blaine Gardner <blaine.gardner@suse.com>
