Enhance the code that migrates the ConfKeyManager's fixed_key to Barbican to also consider the Backup table. When the original key migration feature was added, the encryption key ID was not stored in the Backup table. But now the Backup table contains that field, so the migration code needs to handle that table as well. Whereas the cinder-volume service is responsible for migrating keys in the Volume and Snapshot tables, the cinder-backup service handles migrating keys in the Backup table. Each instance of the service migrates its own entries by matching the "host" field in the corresponding tables. The Backup OVO now inherits from base.CinderComparableObject. This does not affect the object's hash signature, and so the version number does need to be incremented. Closes-Bug: #1757235 Change-Id: Id4581eec80f82925c20c424847bff1baceda2349
