Improve ceph backup driver for incremental backup
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.
Volume backup service with Ceph driver should respect the `--incremental` option for backups. If the incremental flag is not specified then a new full backup will always be created, allowing for subsequent deletion of older incremental backups.
