I'd recommend against using the cloud-init network-interfaces stanza.  It's
in a messy state of porting against "redhat-initscripts" network configuration
vs NetworkManager (and then against systemd-networkd...).

I don't see a serious problem with using `bootcmd`.  The broader role
of cloud-init should just be a bootstrap tool for authentication and such
in order to set up a better systems management tool like Ansible.

See https://github.com/openshift/training/issues/193#issuecomment-120496871
for an example of setting dns=none.
