Volume group "cinder-volumes" not found

Cinder amulet and unit tests started failing at cinder/next rev110 (which was a charm-helper sync @ http://bazaar.launchpad.net/~openstack-charmers/charms/trusty/cinder/next/revision/110).

Amulet and unit tests were passing @ cinder/next rev109 (results @ http://paste.ubuntu.com/11993736/).

NOTE: the functional test fail is with the default lvm-backed storage (not ceph-backed).

While the charm deploys and relates successfully, it appears to have a critical functional break (`cinder create` results in an error-state volume).
