Public bug reported:

When deploying bionic, cloud-init doesn't set the mac address for the
bond or bridge interface, which causes issues when there's expectations
between MAC/IP mappings.

For example, in Bionic:

curtin config sent (/etc/cloud/cloud.cfg.d/50-curtin-networking.cfg): http://paste.ubuntu.com/p/25GnQXQVhn/
neplan config written to netplan (/etc/netplan/50-cloud-init.cfg): http://paste.ubuntu.com/p/XGQRzjGTDm/

The result is that each interface have a different MAC address from
those told in the configuration:

ip addr sh: http://paste.ubuntu.com/p/25GnQXQVhn/

This results in inconsistency which was configured and intended by the
user, vs what it was actually written.

For example, in Xenial, the issue above doesn't exist and the result is
as expected:

curtin config: http://paste.ubuntu.com/p/DmFvryXdwm/
e/n/i config: http://paste.ubuntu.com/p/fsXYpmMzCb/
ip addr sh: http://paste.ubuntu.com/p/wXXSTNfwHK/
