This change updates the ceph.conf update job as follows:
* renames it to "ceph-ns-client-ceph-config"
* consolidates some Roles and RoleBindings
This change also moves the logic of figuring out the mon_host addresses
from the kubernetes endpoint object to a snippet, which is used by the
various bash scripts that need it.
In particular, this logic is added to the rbd-pool job, so that it does
not depend on the ceph-ns-client-ceph-config job.
Note that the ceph.conf update job has a race with several other jobs
and pods that mount ceph.conf from the ceph-client-etc configmap while
it is being modified. Depending on the restartPolicy, pods (such as the
one created for the ceph-rbd-pool job) may linger in StartError state.
This is not addressed here.
