> In additional to YARN-6040, we need to make changes to SchedulingPlacementSet to make
it: 
> 1) Agnostic to ResourceRequest (so once we have YARN-6592 merged, we can add new SchedulingPlacementSet
implementation in parallel with LocalitySchedulingPlacementSet to use/manage new requests
API)
> 2) Agnostic to placement algorithm (now it is bind to delayed scheduling, we should update
APIs to make sure new placement algorithms such as complex placement algorithms can be implemented
by using SchedulingPlacementSet).
