    Partial Revert "Don't pass the DNSServers param in undercloud env"

    This partially reverts commit f1450b3ae8036cfebdc1852ad11769e5585185d7.

    Reason for revert: undercloud_nameservers is supposed to configured
    /etc/resolv.conf. The previous patch broke the link between the
    configuration and the os-net-config configuration to ensure that
    /etc/resolv.conf was updated at install time.

    NOTE: This only affects Train through Victoria as we rewrote the network
    configuration in Wallaby.
