Description of PR

Now when doing non-exclusive resource allocation, queue's max capacity on the partition will be considered to be 100%. In an ideal situation, preemption policy will reclaim resource back when partitoned-resource-request comes back.

But our cluster has not enabled preemption, so a queue may use all resource on the partition and block the partitoned-resource-request of other queues.

In this situation, we hope queue's max capacity will be respect when doing non-exclusive resource allocation.

How was this patch tested?
