Fix killing child sudo process in e2e_node tests
Fixes#29211; re-doing #29380 which was reverted due to cross-platform build failure #29669.
The context is we are trying to kill a process started as `sudo kube-apiserver`, but `sudo` ignores signals from the same process group. Applying `Setpgid` means the `sudo kill` process won't be in the same process group, so will not fall foul of this nifty feature.
~~I also took the liberty of removing some code setting `Pdeathsig` because it claims to be doing something in the same area, but actually it doesn't do that at all. The setting is applied to the forked process, i.e. `sudo`, and it means the `sudo` will get killed if we (`e2e_node.test`) die. This (a) isn't what the comment says and (b) doesn't help because sending SIGKILL to the sudo process leaves sudo's child alive.~~
We do need to use the same 'hack' to access `Setpgid` as the `e2e_node.test` program gets built on Windows (although it doesn't run there).

Run node e2e pull VMs in a separate GCP project
I haven't increased quota yet, so we shouldn't merge until I've done so. This is mostly just testing to see if the rest of the plumbing works.
Part of #27648.

[GarbageCollector] measure latency
First commit is #27600.
In e2e tests, I measure the average time an item spend in the eventQueue(~1.5 ms), dirtyQueue(~13ms), and orphanQueue(~37ms). There is no stress test in e2e yet, so the number may not be useful.

Use latest GCI image based on a regex in Node e2e
This PR also makes it possible to run node e2e against multiple previous images, sorted by creation time. A regex for the image name can be used to instruct node e2e to identify test images.

It can run tests against multiple existing images that match a regex.
GCI images will be using a regex.

Add test for supplemental gid annotation to pv e2e test
Test for feature added in #29119. Adds the annotation to the pv in the PersistentVolumes e2e test. It tests it by checking the output of 'id -G.' Also tests the actual use case of an nfs server by using an nfs server image 'volume-nfs-gid', modified slightly from 'volume-nfs' to have some permissions set.

Cut the client repo, staging it in the main repo
Tracking issue: #28559
ref: https://github.com/kubernetes/kubernetes/pull/25978#issuecomment-232710174
This PR implements the plan a few of us came up with last week for cutting client into its own repo:
1. creating "_staging" (name is tentative) directory in the main repo, using a script to copy the client and its dependencies to this directory
2. periodically publishing the contents of this staging client to k8s.io/client-go repo
3. converting k8s components in the main repo to use the staged client. They should import the staged client as if the client were vendored. (i.e., the import line should be `import "k8s.io/client-go/<pacakge name>`). This requirement is to ease step 4.
4. In the future, removing the staging area, and vendoring the real client-go repo.
The advantage of having the staging area is that we can continuously run integration/e2e tests with the latest client repo and the latest main repo, without waiting for the client repo to be vendored back into the main repo. This staging area will exist until our test matrix is vendoring both the client and the server.
In the above plan, the tricky part is step 3. This PR achieves it by creating a symlink under ./vendor, pointing to the staging area, so packages in the main repo can refer to the client repo as if it's vendored. To prevent the godep tool from messing up the staging area, we export the staged client to GOPATH in hack/godep-save.sh so godep will think the client packages are local and won't attempt to manage ./vendor/k8s.io/client-go.
This is a POC. We'll rearrange the directory layout of the client before merge.

E2E & Node E2E: Move pods test into common directory
This is the 4th part of #29494.
For #29081.
Based on #29092, #29806.
The first commit is squash of all dependent commits. Please only review the last 2 commits.
The 2nd commit migrates pods.go to `common/pods.go`.
Notice that the test `should be schedule with cpu and memory limits` is removed because:
* It doesn't make sense at the node level.
* It should have been tested in scheduler_predicates at the cluster level https://github.com/kubernetes/kubernetes/blob/master/test/e2e/scheduler_predicates.go#L264
The 3rd commit splits pods.go into several pods (nothing is changed, only move code):
* **Liveness probe test:** Moved into `container_probe.go`.
* **Init container test:** Moved into a new file `init_container.go`.
* **Others:** Still in pods.go

This test creates three pods with QoS of besteffort, burstable, and
guaranteed, respectively, which each contain a container that tries to
consume almost all the available memory at a rate of about 12Mi/10sec.
The expectation is that eviction will be initiated when the hard
memory.available<250Mi threshold is triggered, and that eviction will proceed
in the order of besteffort, then burstable. Since guaranteed pods should
only be evicted if something charged to the host uses more resources
than were reserved for it, we currently end the test when besteffort and
burstable have both been evicted.
Note that this commit also sets --eviction-hard=memory.available<250Mi
to enable eviction during tests.

e2e flake: real fix of PodAntiAffinity test
The fix in PR https://github.com/kubernetes/kubernetes/pull/30135 was wrong in using a wrong test condition for an already broken test.
### Summary
The test tries to launch a pod with an anti-affinity annotation, waits 10
seconds and then checks that it is still pending.
But the anti-affinity annotation does not forbid to launch that pod on just
another node that does not have the zone label at all.
This commit changes this behavior by labeling two nodes with the zone label
and then forcing the pod to be launched on one of those two nodes.
**I assume here that a non-existing label is considered as a different label value.**

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.)

Use report-dir in test framework instead.
We already have `report-dir` option in framework test context.
The node e2e framework should use it as well.
