> 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).
