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.
