+enable anyone deploying it to create a cloud tailor-made for any individual use

 message queues, etc. However, the downside to this configurability is that
 certain operations and features aren't supported depending on the configuration.
 These features may or may not be discoverable from the API so the burden is
-often on the user to figure out what the cloud they're talking to supports.
-Besides the obvious interoperability issues with this it also leaves Tempest
-in an interesting situation trying to figure out which tests are expected to

-(assuming one exists). Instead Tempest has to be explicitly configured as to
-which optional features are enabled. This is in order to prevent bugs in the
