[Merge] ~mwhudson/livecd-rootfs/+git/livecd-rootfs:unbreak-live-server-seeding into livecd-rootfs:ubuntu/master

[Dimitri John Ledkov]

The python code probably should move into subiquity main itself.

It should first call `cloud-init status --wait`, then extract autoinstall.yaml.

This way everything is contained inside the subiquity snap.
