Subject: force_detach terminate_connection needs connector
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=6454429b82c8b9316293cf9e4b38d4067b8b72be;p=openstack-build%2Fcinder-build.git

force_detach terminate_connection needs connector

The function force_detach in cinder/api/contrib/admin_actions does not
take a connector in the body of the request. When it calls terminate
connection it passes in an empty dict as the connector:
self.volume_api.terminate_connection(context, volume, {}, force=True)
This patch pulls the connector out of the body of the request, and
throws an exception if it is missing.
