Merge pull request #94059 from ahg-g/ahg-anti-affinity 
Track pods with required anti-affinity

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

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

Special thanks to igraecao for the help in finding the bug

f58abdf966 Use scheduler cache in affinity priority functions 
Make the cache implement NodeLister and expose it to the priority
functions. This way, the priority functions make use of a single cache,
the scheduler's, instead of mixing it with the lister's caches.

Move from glog to klog 
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
