Filter deprecated versions out

* 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)
