Comment 5 for bug 1379373

Paul is right, novaclient can't remove commands because of backward compatibility. Similarly, I'm not sure nova api can remove the baremetal nodes api extensions.

So I'm going to file this under nova api, the extensions should work by proxying requests to ironic. We could have better handling for scenarios when the user hasn't set up ironic (good error message) or maybe disable the baremetal nodes extensions by default.
