Openstackclient 4.0.0 changed the way some properties are displayed
on screen.
Old:
...,"Properties"
...,"volume_backend_name='BACKEND_1'"
New:
...,"Properties"
...,"{u'volume_backend_name': u'BACKEND_1'}"
or
...,"{'volume_backend_name': 'BACKEND_1'}"
This is breaking idempotency on the cinder_type provider, since it
does not detect them correctly. This patch aims at fixing this, by
trying to detect the new format, and using JSON parsing in that case.
