AttributeError: 'Volume' object has no attribute 'instance_uuid' in manager.py retype

[Kurt Martin]

I recieved the following error when attempting to retype a volume.

instance_uuid is no longer on the volume object after multi-attach patch landed

    Fixed access to instance_uuid in retype

    We missed an access to volume['instance_uuid']
    in the multiattach patch. The instance_uuid and attached_host
    were moved into the volume_attachment table.

    This patch changes how we test to see if a volume is available
    or not, but checking the new location.
