Support backup and restore on xiv/ds8k driver

Registered by Alon Marx

Currently xiv/ds8k driver does not support backup and restore functionality. In order to support it we plan to follow implementations in other drivers.

The implementation for backup_volume:
1. create a snapshot (to be deleted before function ends)
2. attach to snapshot
3. run backup_service.backup on the attached snapshot
4. detach from snapshot
5. delete snapshot
Notes:
a. need to take care of cleanups in case of errors: detach and snapshot deletion.
b. the snapshot will take care of any changes in the volume while backup is running

The implementation for restore_backup
1. attach to volume
2. run backup_service.restore on the attached volume
3. detach volume
