I guess this works well with all setting we store inside the VM config (if 
we correctly use pending section).

But what if we allow to reference external sources for cloudinit data?

For example, I can imagine something like:

cloudinit: template=my-cloud-init-data

which simply includes files found in /etc/pve/cloud-init/my-cloud-init-data/

That data can change, so it would be safer to generate an iso, and use rsync
to copy that image when we migrate the VM?
