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.
