As ceph clients expect the ceph_mon config as shown below for Ceph
Nautilus and later releases, this change updates the ceph-client-etc
configmap to reflect the correct mon endpoint specification.
mon_host = [v1:172.29.1.139:6789/0,v2:172.29.1.139:3300/0],
[v1:172.29.1.140:6789/0,v2:172.29.1.140:3300/0],
[v1:172.29.1.145:6789/0,v2:172.29.1.145:3300/0]
