This patch adds a tab for cinder user messages for volumes and snapshots. Cinder user messages shows error details for cinder resources like if we are unable to create a volume due to some failure in cinder it will shows us the reason of failure. Implements blueprint cinder-user-facing-messages Change-Id: I6f1539ffebdf2dfd0a470009e9171e868c2a9ad3
