I'm all for the code being in a separate project - I think this thing
could have users outside of Nova.

I did work up an idea for how it could be done during Folsom
development, but I actually was thinking of it just being a library:


Not much detail there, but BareMetalConnection/BareMetalNode would be in
the library and BareMetalDriver would be the Nova part. I hadn't figured
on this being a service with its own REST API, but perhaps that does
make sense.

However, that does make me wonder whether we'd see desire to plug
alternative baremetal provisioning technologies into that API, in the
same way we see a desire for alternative backends to the Swift API.

Finally, making this a service (with a yet undefined API) rather than a
library makes me think the new project should go through an incubation
period, rather than bypassing incubation the way Cinder did.
