please add view for snapshot dependency to cinder list

[Dafna Ron]

If we try to delete volumes and it has a snapshot we would fail on dependency.
I think being able to see in list which volume has a snapshot and than using show to see which snapshots are linked to it would be helpful.

[root@cougar06 ~(keystone_admin)]# cinder delete 128681f1-8af2-44fc-bcd6-e3075687f67a
ERROR: Invalid volume: Volume still has 1 dependent snapshots (HTTP 400) (Request-ID: req-a857bbcf-b754-4d85-8343-c3435ecaf1f3)

[<email address hidden> ~(keystone_admin)]# cinder help show
usage: cinder show <volume>

Show details about a volume.

Positional arguments:
  <volume> Name or ID of the volume.

[Swapnil Kulkarni (coolsvap-deactivatedaccount)]

I think the snapshot to volume association can be found by using snapshot-list | grep "volume-id" which I think makes sense rather than adding additional field in cinder-list.

e.g.

$ cinder list

+--------------------------------------+-----------+------+------+-------------+----------+-------------+
