Add the toolbox-support and toolbox-experience subpackages
    
    These are intended to be installed into the image if the image doesn't
    use the fedora-toolbox container as the base image - all the packages
    are already preinstalled there.
    
    The support subpackage should be installed to images that intent to
    work flawlessly with toolbox.
    
    The experience subpackage should be installed as well, to provide the
    same experience while working in the container as one would get on the
    host.
