This is mostly uneventful save for us needing to fix our API ref, which
indicated that the 'OS-EXT-IMG-SIZE:size' field shown in the 'show' and
'detail' views was a string rather than an int. You can confirm this is
*not* the case like so:
>>> import openstack
>>> conn = openstack.connect()
>>> conn.conn.compute.get('https://example.com/compute/v2.1/images/detail').json()
(obviously replace 'https://example.com/' with a compute API host)
