Glance charm allows to store images in file, ceph, swift. This changeset adds support for storage of images in Cinder for OpenStack Mitaka or later. Required dependencies are installed on relation to Cinder (inline with Ceph integration). This feature is dependent on resolution of some packaging issues in the glance-store package (see Related-Bug). Related-Bug: 1609733 Change-Id: Ib9d9f28e040b7b2eebb3f5d0ee9ff0773292bdcc
