    [devstack] Switch ironic to uWSGI

    This patch switches ironic API to run under uwsgi,
    and drops support for running ironic API under mod_wsgi
    from ironic's devstack plugin.

    It also effectively moves all jobs except grenade ones to
    run ironic-api under UWSGI as we start to honor the devstack's
    ENABLE_HTTPD_MOD_WSGI_SERVICES variable (which is True by default).

    The new variable in devstack plugin to toggle deployment with uwsgi
    is IRONIC_USE_WSGI, which defaults to (now confusingly named)
    IRONIC_USE_MOD_WSGI for backward compatibility.
