Ways to have additional interfaces working:

• cloud-init script to get list of available ports (or if you know what would be the names of interfaces) and run dhclient INTERFACE: will make it temporarily up. Workaround: use bootcmd instead of runcmd in cloud-init file.
• cloud-init script to get list of available ports (or if you know what would be the names of interfaces) and add that interface in /etc/network/interfaces.d/50-cloud-init.cfg in image (preload) or in deployed VM (afterload).
