Add a ceph-storage node upgrade script for the upgrade workflow

This adds delivery of an upgrade script to any ceph-storage nodes
during the script delivery that comes first during the upgrade
workflow.

The controllers have the ceph-mon whilst the ceph-osds are on the
ceph-storage nodes. The ceph-mons will be updated first as part of
the heat-driven controller upgrade, and ceph-osds on ceph nodes are
upgraded with the upgrade-non-controller.sh tripleo-common script
as with compute and swift nodes.

Also slight rename for the ObjectStorageConfig/Deployment here for
consistency.
