devstack-plugin-ceph-tempest job failing with "KeyError: 'volume_id'" during test_volume_snapshot_backup

[melanie witt]

Recently, a change merged to remove redundant cleanups in the volume backup tests:

https://review.openstack.org/571336

but it had a bug in it where it assumed 'volume_id' and 'snapshot_id' are returned by the backup create API when they are not.

So, the devstack-plugin-ceph-tempest is failing with the following error:

Traceback (most recent call last):
  File "/opt/stack/tempest/.tox/tempest/local/lib/python2.7/site-packages/cinder_tempest_plugin/api/volume/test_volume_backup.py", line 44, in test_volume_snapshot_backup
    self.assertEqual(volume['id'], backup['volume_id'])
KeyError: 'volume_id'

We must do a GET backup in order to obtain the 'volume_id' and 'snapshot_id' for a particular backup before doing the asserts.

This issue was fixed in the openstack/cinder-tempest-plugin 0.2.0 release.
