queue's deserve can not be returned back when other queue's tasks are all not preemptable
What is the problem you're trying to solve
image there are two queues: A and B, and the cluster have 10GPUs, and both A and B have a deserved with 5GPUs and Capability with 10GPUs. Now, user submit jobs with not preemptable tasks to queue A and use up 10GPUs. Then user submit jobs to queue B can not be scheduled.
Describe the solution you'd like
To limit only tasks be preemptable can be scheduled between a queue's deserved and capability in allocate action.

Could You elaborate a bit how user can deploy non reclaimable task if queue is reclaimable? I'm just curious.

@lowang-bh As far as I understand issue is with the fact, that non preemtable task should be reclaimable, but it's not. And I will ask again - how do You specify if the task is preemtable? I mean it would be much easier to find proper place in the code which is responsible for skipping non preemtable workloads.
You mean volcano.sh/preemptable: "false" annotation?
