Enable rack based affinity placement in solver scheduler
This blueprint discusses the rack-based affinity scheduling scenarios:
- same_rack/
- tenant rack constraint to limit the number of racks that a tenant's instances can spread across. This may help improve ToR network usage.
Three constraint classes are planned to be implemented:
- SameRackConstraint
- DifferentRackCo
- TenantRackConst
