A dhclient configuration option is used to add localhost to resolv.conf, but this does not work for Ipv6 clusters. We must switch to a script run by Networkmanager instead. https://github.com/openshift/installer/pull/2982
Verified on 4.4.0-0.nightly-2020-02-11-124749 on the boostrap VM: [core@localhost ~]$ cat /etc/resolv.conf # Generated by NetworkManager nameserver 127.0.0.1 nameserver fe80::5054:ff:feab:c912%ens3 nameserver fd2e:6f44:5dd8:c956::1
