vgpu work in Stein

Registered by Naichuan Sun

The work in blueprint: vgpu-rocky is not finished. This BP to track the change in Stein to implement the remain functions defined in the following spec.
https://specs.openstack.org/openstack/nova-specs/specs/queens/implemented/add-support-for-vgpu.html

- support traits (display resolution and display heads)
- move vGPU resource to N-RP so it can support multiple vGPU types in single compute node.

This is essentially abandoned at this point for Stein and should probably be deferred to Train. -- mriedem 20190224

We are two days from Stein feature freeze and this is not ready so I'm going to drop it from planning for Stein. If you plan to pursue this in Train please re-propose the spec for re-approval in Train. -- mriedem 20190305
