nodes or compute nodes), and the external-ceph-guide miss storage node,
this patch to fix it.

=======================
When using external Ceph, there may be no nodes defined in the storage group.

In this case, operator should add some nodes to the storage group, all the
nodes where cinder-volume and cinder-backup will run:
::
[storage]
