    Create element to purge resolv.conf

    We should be managing the network configuration with os-net-config or
    elsewhere so we should not be providing a nameserver in resolv.conf
    in overcloud images. This element will be used to ensure that the
    resolv.conf of the overcloud-full image should not contain any
    nameservers.
