Add assertions to attached volume retype test
Previously only the volume type and timestamp data was checked when
retyping an attached volume. This change adds additional assertions to
ensure the volume state remains `in-use`, volume migration state is
`success` and the same `volume_id` remains attached to the instance
after the retype completes. This final check ensures that nova has
correctly called the os-migrate_volume_completion cinder API.
