Add host/port/api_version to tempest.conf

* Something exposed by LP #992096 was that the image
  tests were broken because the URL returned from the
  service catalog was no longer including a version
  identifier. The fix in Tempest was to pass the configure_via_auth=False
  parameter to the glance.client.Client constructor. However, in order
  for this to work, the host/port in the [image] section of the
  Tempest configuration file needs to be set
