74c5b4e4be Merge pull request #28459 from ping035627/ping035627-patch-0704 
Automatic merge from submit-queue

Optimise the process of the CalculateSpreadPriority in selector_spreading.go

It had better inspect if the nodeLister is normal first in the CalculateSpreadPriority in selector_spreading.go. If the nodeLister.List return error, the function return directly, not need deal the serviceLister and controllerLister and replicaSetLister.

4e91166bc6 Use PreferAvoidPods annotation to avoid pods being scheduled to specific node. 
1. define PreferAvoidPods annotation
2. add PreferAvoidPodsPriority
3. validate AvoidPods in node annotations

6aa16c744b When scheduling, spread between zones if labeled 
We already spread across nodes; we modify this spreading preference to
spread across zones when nodes are labeled with zone information.

fad1968023 Adjust V level for scheduler messages 
The "Combined requested resources" message becomes excessive as
the cluster fills up, drop it down to V(2)

Put an explicit V(2) on the only other scheduler Infof call that didn't
have V specified already.
