* api_v2 version of volume service and api_v1 version
of image service are deprecated, but were discovered
and set to True.
* The patch fixes that by checking the status of the
version.
* The patch also adds a deprecated version to fake
services, which are used by unit tests.
* For backward compatibility of python-tempestconf with
older relesies of OpenStack, the patch doesn't remove
deprecated versions (they're not deprecated in Pike
and older)
