This patch collects the resource requests from each neutron port involved in a server create request. Converts each request to a RequestGroup object and includes them in the RequestSpec. This way the requests are reaching the scheduler and there they are included in the generation of the allocation_candidates query. This patch only handles the happy path of a server create request. But it adds couple of TODOs to places where the server move operations related code paths need to be implemented. That implementation will be part of subsequent patches. Note that this patch technically makes it possible to boot server with one neutron port that has resource request. But it does not handle multiple such ports or SRIOV ports where two PFs are supporting the same physnet as well as many server lifecycle operations like resize, migrate, live-migrate, unshelve. To avoid possible resource allocation inconsistencies due to the partial support nova rejects any requests that involves such ports. See the previous patches in this patch series for details. Also note that the simple boot cases are verified with functional tests and in those tests we need to mock out the above described logic that reject such requests. See a more background about this approach on the ML [1].
