Add concept of resource providers (partial)

Registered by Jay Pipes on 2015-10-13

This blueprint aims to address the problem of Nova assuming all resources are provided by a single compute node by introducing a new concept -- a resource provider -- that will allow Nova to accurately track and reserve resources regardless of whether the resource is being exposed by a single compute node or some shared pool or service.

Marking this as partially complete, as we hit the deadline -johnthetubaguy 2nd march 2016

I've re-opened this for newton, there is only one remaining change:

https://review.openstack.org/#/c/282442/

It's just easier to re-open this and continue the work there given the big dependency chain we have.
