This fixes the `go vet` errors brought about by go 1.7 testing re (#28742).

The are all pretty trivial and mostly related to literal composites.

Copy something to values in parameters won't change them in go. So, remove it to avoid making people confused.

SchedulerExtender: add failedPredicateMap in Filter() returns

Fix #25797. modify extender.Filter for adding extenders information to “failedPredicateMap” in findNodesThatFit.
When all the filtered nodes that passed "predicateFuncs" don’t pass the extenders filter, the failedPredicateMap hasn’t the extenders information, should add it, I think. So when the length of the “filteredNodes.Items” is 0, we can know the integral information. (The length of the “filteredNodes.Items” is 0, may be because the extenders filter failed.)

821ff657f9 Merge pull request #27199 from derekwaynecarr/disk_eviction 
Automatic merge from submit-queue

Initial support for pod eviction based on disk

This PR adds the following:

1. node reports disk pressure condition based on configured thresholds
1. scheduler does not place pods on nodes reporting disk pressure
1. kubelet will not admit any pod when it reports disk pressure
1. kubelet ranks pods for eviction when low on disk
1. kubelet evicts greediest pod

Follow-on PRs will need to handle:

1. integrate with new image gc PR (https://github.com/kubernetes/kubernetes/pull/27199)
1. container gc policy should always run (will not be launched from eviction, tbd who does that)
  1. this means kill pod is fine for all eviction code paths since container gc will remove dead container
1. min reclaim support will just poll summary provider (derek will do follow-on)
1. need to know if imagefs is same device as rootfs from summary (derek follow-on)

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.
