Change default DNS nameserver used by Kubernetes pods

This can be applied generically but usually applies to Linux nodes that have a local caching nameserver running, which means pointing to an IP in the loopback range (127.0.0.0/8). Ubuntu 18.04 Bionic Beaver does this by default.

Option 1: Change host configuration

sudo systemctl mask systemd-resolved
rm -f /etc/resolv.conf
sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
