Enable affinity placement in solver scheduler for network optimization purpose
We should let the scheduler be able to place instances close to those existing ones in racks that tenants are located and networks that tenants are using. Rack based affinity costs will be implemented, which will be able to help optimizing tenant distribution and tenant net's distribution as well. This may help improve ToR network usage.
