cloud: Consistent device naming
    
    Use consistent network device names for network devices instead of
    forcing the old "ethX" names from pre-2017. This ensures that
    specialized network devices, such as SR-IOV devices, are easy to
    recognize and configure inside a Fedora instance on a public cloud or
    OpenStack cloud.
