> In case of long running tasks, reduce node resource should balloon out

> In current design and implementation, when we decrease resource on node to
> less than resource consumption of current running tasks, tasks can still be
> running until the end. But just no new task get assigned on this node
> (because AvailableResource < 0) until some tasks are finished and
> AvailableResource > 0 again. This is good for most cases but in case of long
> running task, it could be too slow for resource setting to actually work so
> preemption could be used here.
