> As mentioned by [~asuresh], SELF means target allocation tag same as allocation tag of the scheduling request itself. So this is not a new type for sure, it is still ALLOCATION_TAG type.
> If we really want this functionality, we can build this in PlacementConstraints, but I'm doubtful about this since copying allocation tags from source is just a trivial work.
