When userProvisionedDNS is enabled, a static DNS pod is run on the bootstrap node to provide DNS while control plane nodes are coming up. So, the resolv.conf on the bootstrap node should point to this local DNS while is running on localhost with IP 127.0.0.1.
We also need to make sure this resolv.conf entry does not get overwritten by NetworkManager when the bootstrap node is coming up.
