I think there's already good consensus on this and the idea is to use
entry points and stevedore to achieve it.

See:

  https://blueprints.launchpad.net/nova/+spec/entrypoints-plugins
  https://review.openstack.org/11027
  https://review.openstack.org/15030

The end result is exactly that

  compute_driver=libvirt

will work, along with backwards compat for the original name.

It just needs to be resurrected and finished off.

Cheers,
Mark.
