This adds "openstack-ci-mirrors" element which performs various
settings to get builds using local mirrors. As a first step, we
convert ubuntu-minimal jobs
The main trick is that since infra mirrors are created with rerepo
they are not signed (they are recreated, not cloned, and not signing
is seen as a feature in that it deters external use). So we need to
instruct debootstrap to ignore signing and also turn it off for
in-chroot apt. Other than that, the existing DIB_DISTRIBUTION_MIRROR
works to redirect installs.
Remove "restricted" as it's not mirrored, and I don't think we want it
in here by default.
(I think DIB_DISTRIBUTION_MIRROR is a bit of an anti-pattern, because
it leaves the mirrors in the final image -- just because you use them
to build, doesn't mean you want them at runtime). But we don't need
to fix that now, and we don't use any created images.)
This pauses fedora testing until the next change, which moves to using
local mirrors for testing on fedora/centos

We somewhat discussed skipping qcow2 generation previously in
I9372e195913798a851c96e62eee89029e067baa1. As recent issues with PPC
testing have shown, we are not actually testing the "vm" element and
hence the bootloader path in the functional tests.
I don't think we need to test this on every element; it overlaps
somewhat with the testing done by the nodepool jobs which build full
images and boot them. I also didn't want to introduce a separate run
for this. Thus it seems valuable to at least have one element
enhanced to do this installation and conversion in our default tests
for basic sanity.
This disables qcow generation by default, as per the other change, but
allows an element to drop a file that will override the output
formats. The Xenial element is modified to produce a qcow2 using
this, and also introduces a dependency on the "vm" element so it tries
to install the bootloader.
We now exit if the .qcow2 fails to build as well.
