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.

Automatic merge from submit-queue

Change storeToNodeConditionLister to return []*api.Node instead of api.NodeList for performance



Currently copies that are made while copying/creating api.NodeList are significant part of scheduler profile, and a bunch of them are made in places, that are not-parallelizable.

Optimize priorities in scheduler

It's probably easier to review it commit by commit, since those changes are kind of independent from each other.
