This is a code improvement to reuse ceph monitor doscovering function
in different templates. Calling the mentioned above function from
a single place (helm-infra snippets) allows less code maintenance
and simlifies further development.
Rev. 0.1 Charts version bump for ceph-client, ceph-mon, ceph-osd,
ceph-provisioners and helm-toolkit
Rev. 0.2 Mon endpoint discovery functionality added for
the rados gateway. ClusterRole and ClusterRoleBinding added.
Rev. 0.3 checkdns is allowed to correct ceph.conf for RGW deployment.
Rev. 0.4 Added RoleBinding to the deployment-rgw.
Rev. 0.5 Remove _namespace-client-ceph-config-manager.sh.tpl and
the appropriate job, because of duplicated functionality.
Related configuration has been removed.
Rev. 0.6 RoleBinding logic has been changed to meet rules:
checkdns namespace - HAS ACCESS -> RGW namespace(s)
