OpenStack backups

Backups allow storing backups of instances outside of an OpenStack deployment and restoring it on other deployment.

On backup creation Waldur creates cinder backups for each volume of the instance, stores instance metadata and exports and saves metadata records of cinder backups.

On backup restoration Waldur creates cinder backups in a new tenant, based on saved metadata records. After that it creates new volumes and restores cinder backups into them. Finally, Waldur creates new instance based on restored volumes and backup metadata.

REST API
