it as ALLOCATION_SLACK.

@Joseph, I can not remenber where did you append your comments about this topic; but it seems
you're OK to offer both `stateless.reserved` & `ALLOCATION_SLACK` of the same role, right?
But how framework developer distinguish `stateless.reserved` & `ALLOCATION_SLACK` of its?
If it launch task in `ALLOCATION_SLACK` and `stateless.reserved`, the task in `ALLOCATION_SLACK`
was terminated immediately; it just increases overhead of cluster instead of resource utilization.
