The Application EcoSystem Working Group realized during the mid-cycle meetup in Philadelphia that there is no way to get the capabilities of an Openstack cloud so that applications can measure their compatibility against that cloud.  In other words,  if we create an Openstack App Marketplace and have developers make apps to be in that marketplace, then we'll have no way for apps to verify that they can run on that cloud.  We'd like to ask that there be a standard set of API calls created that allow a cloud to list its capabilities.  The cloud "features" or capabilities list should return True/False API responses and could include but is not limited to the below examples.  Also, https://review.openstack.org/#/c/162655/ may be a good starting point for this request.
