Usage

For example, the subordinate would handle the cinder-backend.connected state with something like:

@when('cinder-backend.connected')
def configure_cinder(cinder_principal):
    config = {'api-endpoint': '1.2.3.4',
              'admin-username': 'admin',
              'admin-password': 'openstack',
              'api-version': '1.0'}
    cinder_principle.configure_principal(
      backend_name='my_backend', configuration=config)
