    Remove old style ssl setting

    devstack is using apache as a ssl proxy for wsgi api service.
    Current tacker does not support it. We remove it for the time being

    This patch also skip scale unit tests which failed due to
    heat translator change. The unit test will be enabled at
    another patch.
