Enhancement on the testcase to cover more possibilities
...
This change enriches the testcase of `TestPriorityQueue_MoveAllToActiveOrBackoffQueue`
to cover the case that pods in the unschedulableQ could be moved to activeQ after the
backing off.

Track pods with required anti-affinity
...
This is a performance optimization that reduces the overhead of inter-pod affinity PreFilter calculaitons. Basically
eliminates that overhead when no pods in the cluster use required pod anti-affinity. This offered 20% improvement on 5k clusters for preferred anti-affinity benchmarks.

Change nodeInfolist building logic in scheduler
...
This commit transforms the next() function of the scheduler node
tree into a listNodes() function that directly returns a list of
nodes, going through the zones in a round-robin fashion. This
removes the flawed logic of the next() function.

Keep track of remaining pods when a node is deleted.
...
The apiserver is expected to send pod deletion events that might arrive at a different time. However, sometimes a node could be recreated without its pods being deleted.
