Refactor namespace fairshare function. #2757

Merged

Current allocate action must sort namespace, then queue in each namespace, then jobs in a queue of single namespace, which is time-costing and inefficient, just to realize namespace-fairshare. And, since allocate action worked differently with preempt and reclaim action, it kept causing comlicated issues in evict and re-allocate in next session. So I would rather realize namespace-fairshare by other methods instead of sort namespaces in allocate action.

Yes, queue should be pushed in queues only on the first job in the queue is picked. I'll modify it, thank you.
