Stephen Finucane 340ef02e06 libvirt: Deprecate support for non-QEMU/KVM backends
None of these backends has had upstream testing in a very long time, if
ever, and their usage levels are unknown. Deprecate them now so that we
can at least remove the worst of them (UML, Xen) in the next cycle.

Support for the ``xen``, ``uml``, ``lxc`` and ``parallels`` libvirt
backends, configured via the ``[libvirt] virt_type`` config option, has
been deprecated. None of these drivers have upstream testing and the
``xen`` and ``uml`` backends specifically have never been considered
production ready. With this change, only the ``kvm`` and ``qemu`` backends
are considered supported when using the libvirt virt driver.
