[Merge] ~vorlon/ubuntu-seeds/+git/ubuntu:seed-lxd-installer into ~ubuntu-core-dev/ubuntu-seeds/+git/ubuntu:kinetic

[Paride Legovini]

Do we actually need to make sure lxd-installer gets removed in a full install? Keeping it looks fully harmless, and after all there's nothing removing lxd-installer from a minimal install after it gets used to install the lxd snap.
