The main goal behind this todo item was to get liblxc support into
OpenStack which is now being done in a different way (directly as an
OpenStack plugin, bypassing the libvirt layer which is more suited to
handling VMs than containers).

I think I've already said so here a dozen time but let's clarify it
again, libvirt-lxc and lxc are entirely different projects which
unfortunately happen to share a name, there's not a single line of code
in common between those two and their feature set is widely different
too.

While it'd be nice to have libvirt-lxc be based on liblxc, that doesn't
seem to be the direction that project is currently heading towards.
Having a second libvirt driver would be an option but given that
OpenStack is now working towards a container API which will let us get
direct LXC integration, there's not many insentive for us to divert time
from other work in order to work on such a plugin.
