    Minimise distro packages installed into the lxc image
    
    This patch removes all packages from the lxc image cache preparation
    which are not required to run the 'setup-hosts' playbook, or pass the
    lxc_hosts role tests.
    
    Additional packages should be installed by the ansible roles which
    further customise the containers.
