4b2c054e59 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.

a8873e1a43 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.

dfe9e413d9 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.

Partial revert of https://github.com/kubernetes/kubernetes/pull/86964

33a7e94b6a Create new slices to avoid modify original fake data 
When create fake data for the nodeTree unittests, The 'append' is invoked
on the common fake data set. That makes the unittests is running with unexpected
fake data after that.

Fix scheduler issue with nodetree additions 
When nodes are added in multiple zones at once, the nodeTree next
function does not return a correct list of nodes but repeats some
This commit resets the index before starting to call next() to
prevent this issue

Move unschedulable Pod to internal schedulingQ synchronously 
- use in-cache Pod instead of real-time Pod (by calling API server) to mark it as unschedulable
  in internal schedulingQ
- remove the backoff logic as now we don't call API server
- the whole logic is changed to a synchronous call
