> There're 3 stages in ProportionalCapacityPreemptionPolicy,
> # Recursively calculate {{ideal_assigned}} for queue. This is depends on
> available resource, resource used/pending in each queue and guaranteed
> capacity of each queue.
> # Mark to-be preempted containers: For each over-satisfied queue, it will
> mark some containers will be preempted.
> # Notify scheduler about to-be preempted container.
> We need respect labels in the cluster for both #1 and #2:
> For #1, when calculating ideal_assigned for each queue, we need get
> by-partition-ideal-assigned according to queue's
> guaranteed/maximum/used/pending resource on specific partition.
> For #2, when we make decision about whether we need preempt a container, we
> need make sure, resource this container is *possibly* usable by a queue which
> is under-satisfied and has pending resource.
> In addition, we need to handle ignore_partition_exclusivity case, when we
> need to preempt containers from a queue's partition, we will first preempt
> ignore_partition_exclusivity allocated containers.
