[Scheduler] Improve pod log output debuggability

Address issue is #30675

The result of my expirments shows that both `glog.Infof("%v", pod)` and `glog.Infof("%+v", pod)` can't output useful information of a pod, it can only output `kind:"" apiVersion:""`. 

`%#v` can output the whole content of pod, but it seems too much!

So, my opinion is output pod info use the format of `%v` to print`pod.Namespace/pod.Name` instead of the pod **object** in both [here](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/scheduler.go#L96) and [here](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/scheduler.go#L100).

update comment info for scheduler binding fails

Since the process logic for scheduler binding failed has changed, I think we should update the comment information to avoid make people confused :)

The related issue is #30611.

@wojtek-t What do you think about it ?

Thanks!

ClusterAutoscaler-friendly scheduler priority function that promotes well-used nodes

It will help cluster autoscaler to put pods on nodes that are unlikely to be deleted soon due to low usage. Otherwise a pod may be frequently kicked from one node to another. A flag that enables it when CA is on will be added in a separate PR.

Fixes: #28842

remove duplicated nodeinfo.pods assignment

There are duplicated assignments for nodeinfo.pods, one place is [here](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/schedulercache/node_info.go#L139) and the other one is [here](https://github.com/kubernetes/kubernetes/blob/master/plugin/pkg/scheduler/schedulercache/node_info.go#L147). 

I think we can remove one.

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.

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)
