    Fix nova scheduler down after first docker restart

    Due to a Docker bug [1] we cannot use Docker to send
    SIGHUP to the container because it will mark it as
    stopped.
    This patch sends the signal directly to the process,
    bypassing Docker.

    'changed_when: false' is also removed from the
    relevant task as it definitely changes the state.
    In the future we could do the refresh only if
    there really is a need for another one.
