This converts the special cases in the is_service_enabled() function to call individual functions declared by the projects. This allows projects that are not in the DevStack repo and called via the extras.d plugin to handle an equivalent service alias. * Ceilometer * Cinder * Glance * Neutron * Nova * Swift TODO: remove the tests from is_service_enabled() after a transition period Patch Set 2: Rebased Change-Id: Ic78be433f93a9dd5f46be548bdbd4c984e0da6e7
