It appears that gophercloud's "AllowReauth" AuthOption doesn't actually do anything, and the keystone/auth token is never refreshed. Eventually it expires and all OpenStack calls receive HTTP 401 responses. This change reauthenticates every time the Instances() or TCPLoadBalancer() API object is requested. This is more frequently than required, but exposing token expiry information will require gophercloud surgery.
