Bug Description

The affinity/anti-affinity checks of Nova do not work correctly since Pike [1] because upcalls from the computes to the scheduler (or other control services) cannot occur in deployments with multiple (v2) cells [2]. These affinity/anti-affinity checks have to be enabled for instance reservation.

Need a design to fix the problem though the use of placement API in Blazar is still under the discussion.
