manchandavishal 79ff0d45c4 Add cinder-user-facing messages
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
