Cinder get-capabilities tests
Cinder allows getting capabilities for a storage back end Added: - Api for get-capabilities - Documentation reference for cinder show_pools Tests: - Test get capabilities for a given back end - Test get volume stats Note: Only admin has the privileges to perform get-capabilities action, by default.
