Bug description:
  [Impact]

  The customer faced issue when they are using nova with 3par storage.
  they can't delete volume if there is children and it is attached to vm.

  it makes sense they can't delete it as the children has attachment but
  nova should expose proper error when trying deletion.

  [Test Case]

  The customer has the required hardware for testing this.

  Volume->Snapshot->Volume2
  Volume2 is attached to some VM.
  and can't delete Volume without proper error msg.

  [Where problems could occur]
  This is related to hpe3par storage.
  snapshot handling could be issue with this patch.
  deleting volume could be issue with this patch.

  [Others]

  Original Desc

  When we try to delete a snapshot, we flatten it's dependent volumes by copying them to a new volume and deleting the original one.
  We fail to copy the volume when it has children and it is not handled in the code.

  : hpe3parclient.exceptions.HTTPConflict: Conflict (HTTP 409) 32 -
  volume has a child
