fixes:
  - Fixed issue where all Ceph RBD backups would be incremental after the
    first one. The driver now honors whether ``--incremental`` is specified or
    not.
Support Incremental Backup Completion In RBD Ceph RBD backend ignores the `--incremental` option when creating a volume backup. The first backup of a given volume is always a full backup, and each subsequent backup is always an incremental backup. This behavior makes it impossible to remove old backups while keeping at least one recent backup. Since Cinder will not find the latest_backup id as parent_id if '--incremental=False', so we can use the parent_id to ensure whether do the full backup in rbd driver or not. If the incremental flag '--incremental' is not specified, this patch will always create a new full backup for rbd volume.
