Most of our distros support DIB_DISTRIBUTION_MIRROR for setting the
mirror to be used when building. This has a major downside where if
someone would like to create a static configuration for building various
distro images it cannot set DIB_DISTRIBUTION_MIRROR (think of the case
where we want to run our tests).
By adding support for DIB_$DISTRO_DISTRIBUTION_MIRROR this problem is
resolved.

debootstrap is not debian or ubuntu specific. We can make a debootstrap
element that knows how to do all of the things, and then a
debian-minimal and ubuntu-minimal image that use it. Finally, make
the debian element simply be a collection of the extra things we do to
make it look like a cloud-init based cloud image.

There are times when a much more stripped down base image is desired
over the distro cloud images. For instance, Infra would like some base
images that do not have cloud-init or really much of anything else. This
is easy to accomplish with debootstrap and rinse.
