Merge lp:~mwhudson/livecd-rootfs/subiquity-auto-mount into lp:livecd-rootfs

[Michael Hudson-Doyle]

Mount a partition of fixed uuid at /subiquity_config for subiquity to load. Create an appropriate drive file this:

$ mkfs.ext4 -U 00c629d6-06ab-4dfd-b21e-c3186f34105d ../can.ext4
$ sudo mount ../can.ext4 /mnt
$ sudo cp examples/answers.yaml /mnt/
$ sudo umount /mnt

It's subiquity_config not subiquity-config because you can't commit subiquity\x1dconfig.mount to bzr.
