    Use Python 3 for mod_wsgi in cyborg and monasca on Debian/Ubuntu

    In Train kolla switched to Python 3 in Debian and Ubuntu source images.
    For services running under httpd with mod_wsgi, they should install
    libapache2-mod-wsgi-py3 rather than libapache2-mod-wsgi. This was done
    for most images, but cyborg and monasca were omitted. This change fixes
    that.
