Jonathan Rosser 786c4fcf18 Switch all base images to be built locally rather than downloaded
This patch switches the debian/ubuntu OS to build their lxc base
images locally using debootstrap rather than download a pre-built
lxc image. This unifies the approach with Centos-8 which is already
building a local image using dnf.

The LXC cache prestage tasks are removed, and all variables
associated with the download of the lxc image are removed from
defaults/main.yml.

A new variable lxc_apt_mirror is introduced, which is passed to
debootstrap to provide the apt source that the container rootfs
should be built from.
