This going to be fairly complicated to make much headway on, unless the resource_provider objects are moved out from under nova/objects. there registers all those objects, each of which imports things from all over the nova hierarchy. One notable example are the ec2 objects which import nova/api/ec2/ec2utils which imports dogpile so it can memoize some operations (are they ever called?).

Also, nova/ imports oslo_service and eventlet, neither of which placement wants to see. This could perhaps be moved back to nova/cmd and wherever else is actually required.
