Automatic merge from submit-queue

First step of optimizing PodAffinity priority function

Ref #26144 

This is obviously only a first step - I will continue working on this code. However, this is changing the general scheme of computations to what is described in: https://github.com/kubernetes/kubernetes/issues/26144#issuecomment-232612384

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.
