We have the ability to register custom parser/formatting callbacks
for namespaces that we use for QEMU cli arg passthrough.

I'm thinking we'd be better off defining a custom namespace for
the test driver & using that for this element.

Of course we'd have to extend these namespace hooks to the other
types of objects, since we only have it for domains currently.
