I believe ironic was an early example of a client library we hot-loaded,
and I believe at the time we said this was a pattern we were going to
follow. Personally, I think this makes plenty of sense and I think that
even moving things like the python-libvirt load out to something like
this to avoid hyperv people having to nuke it from requirements makes
sense.

This seems like a terrible reason to make everyone install ironicclient
(or the z/vm client) on their systems at runtime.
