The Reef release disallows internal pools from being created by
clients, which means the ceph-client chart is no longer able to
create the .rgw.root pool and configure it. The new ceph-rgw-pool
job deletes and re-creates the ceph-rbd-pool job after ceph-rgw has
been deployed so that job can configure the .rgw.root pool
correctly.
