Accidentally (on purpose), I proposed a platform support matrix for QEMU
that has the same rules as libvirt. So broadly speaking both projects
will target the same platforms at any given point in time.

None the less we should *NOT* remove platforms from libvirt-ci as the
first step. We should remove the platforms from usage in all projects
first. Removing from libvirt-ci should be the last thing.

This is because while projects broadly follow the same goals, the
timeframe in which those goals are applied may not line up exactly.
There can be constraints from the software release cycles. QEMU is
about to enter freeze, but if they encounter problems in CI they
still want to be able to pull in updates from libvirt-ci, without
Ubuntu 18.04 support being ripped out from under their feet.

Daniel
