Quiesce admin action for consistent snapshot

Registered by Tomoki Sekiyama on 2014-01-31

Currently we need to quiesce filesystems (fsfreeze) manually before snapshotting cinder volumes attached to active instances to create consisten backups. This should be automated when QEMU Guest Agent is enabled.

To achieve the automated quiescing, Nova should expose an admin action to quiesce the guest file systems for Cinder.
