Switched watches in tests require ResourceVersion to be passed
For testing the Watches are not sufficient in that it might miss the event of transitioning a Pod from one state to another which might happen before we start Watching events. To remedy this, I'm proposing to switch to Gets to always read the actual state of a Pod.
@smarterclayton this fixes https://github.com/openshift/origin/issues/9192 and hopefully all `gave up waiting for pod...` flakes

Don't repeat the program name in healthCheckCommand.String()
The name is in both `Path` and `Args[0]`, so start printing args at 1.
Also refactor to avoid an extra space character in the output.
I pondered whether `healthCheckCommand.String()` should check if the slice is empty, to avoid a panic, but it didn't check for `Cmd==nil` before.

Return (bool, error) in Authorizer.Authorize()
Before this change, Authorize() method was just returning an error, regardless of whether the user is unauthorized or whether there is some other unrelated error. Returning boolean with information about user authorization and error (which should be unrelated to the authorization) separately will make it easier to debug.

Node E2E: Make it possible to share test between e2e and node e2e
This PR is part of the plan to improve node e2e test coverage.
* Now to improve test coverage, we have to copy test from e2e to node e2e.
* When adding a new test, we have to decide its destiny at the very beginning - whether it is a node e2e or e2e.
This PR makes it possible to share test between e2e and node e2e.
By leveraging the mechanism of ginkgo, as long as we can import the test package in the test suite, the corresponding `Describe` will be run to initialize the global variable `_`, and the test will be inserted into the test suite. (See https://github.com/onsi/composition-ginkgo-example)
In the future, we just need to use the framework to write the test, and put the test into `test/e2e/node`, then it will be automatically shared by the 2 test suites.
This PR:
1) Refactored the framework to make it automatically differentiate e2e and node e2e (Mainly refactored the `PodClient` and the apiserver client initialization).
2) Created a new directory `test/e2e/node` and make it shared by e2e and node e2e.
3) Moved `container_probe.go` into `test/e2e/node` to verify the change.

[flake fix] Wait for the podInformer to observe the pod
Fix#29065
The problem is that the rc manager hasn't observed pod1, so it creates another pod and scales down, pod1 might get deleted. To fix it, wait for the podInformer to observe the pod before running the rc manager.
Marked as P0 as it's fixing a P0 flake.

Drop support for --gce-service-account, require activated creds
Now that `gcloud auth activate-service-account` is in remove support in the test framework for default service accounts -- testing GCE/GKE now requires prior gcloud activation.
This commit ensures that `logPodStartupStatus` does not leak
running `time.Ticker` instances. Upon termination of the consuming
routine, we stop the ticker.
Before this change, Authorize() method was just returning an error,
regardless of whether the user is unauthorized or whether there

[GarbageCollector] Let the RC manager set/remove ControllerRef
What's done:
* RC manager sets Controller Ref when creating new pods
* RC manager sets Controller Ref when adopting pods with matching labels but having no controller
* RC manager clears Controller Ref when pod labels change
* RC manager clears pods' Controller Ref when rc's selector changes
* RC manager stops adoption/creating/deleting pods when rc's DeletionTimestamp is set
* RC manager bumps up ObservedGeneration: The [original code](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/replication/replication_controller_utils.go#L36) will do this.
* Integration tests:
* verifies that changing RC's selector or Pod's Labels triggers adoption/abandoning
* e2e tests (separated to #27151):
* verifies GC deletes the pods created by RC if DeleteOptions.OrphanDependents=false, and orphans the pods if DeleteOptions.OrphanDependents=true.
TODO:
- [x] we need to be able to select Pods that have a specific ControllerRef. Then each time we sync the RC, we will iterate through all the Pods that has a controllerRef pointing the RC, event if the labels of the Pod doesn't match the selector of RC anymore. This will prevent a Pod from stuck with a stale controllerRef, which could be caused by the race between abandoner (the goroutine that removes controllerRef) and worker the goroutine that add controllerRef to pods).
- [ ] use controllerRef instead of calling `getPodController`. This might be carried out by the control-plane team.
- [ ] according to the controllerRef proposal (#25256): "For debugging purposes we want to add an adoptionTime annotation prefixed with kubernetes.io/ which will keep the time of last controller ownership transfer." This might be carried out by the control-plane team.

Support terminal resizing for exec/attach/run
```release-note
Add support for terminal resizing for exec, attach, and run. Note that for Docker, exec sessions
inherit the environment from the primary process, so if the container was created with tty=false,
that means the exec session's TERM variable will default to "dumb". Users can override this by
setting TERM=xterm (or whatever is appropriate) to get the correct "smart" terminal behavior.
```

This allows us to start building real dependencies into Makefile.
Leave old hack/* scripts in place but advise to use 'make'. There are a few
rules that call things like 'go run' or 'build/*' that I left as-is for now.

node_e2e: configure gce images via config file
This file provides the abiliy to specify image project on a per-image
basis and is more extensible for future changes.
For backwards compatibility and local development convenience, the
existing flags are kept and should work.
The eventual goal is to be able to source some images, such as the CoreOS one (and possibly containervm one) from their upstream projects and do all new configuration changes via a cloud-init key added to the image config.
This PR is a first step there. A following PR will add a config key of `cloud-init` or `user-data` and migrate the CoreOS e2e to use that.
This motivation is driven by the fact that currently the changes needed for the CoreOS image can all be done quickly in cloud-init and this will make it much easier to update the image and ensure that changes are applied consistently.

Node E2E: Prep for continuous Docker validation node e2e test
Based on https://github.com/kubernetes/kubernetes/pull/28516, for https://github.com/kubernetes/kubernetes/issues/25215.
https://github.com/kubernetes/kubernetes/pull/26813 added support to run e2e test on gci preview image and newest docker version.
This PR added the same support to node e2e test.
The main dependencies of node e2e test are `docker`, `kubelet`, `etcd` and `apiserver`.
Currently, node e2e test builds `kubelet` and `apiserver` locally, and copies them into `/tmp` directory in VM instance. GCI also has built-in `docker`. So the only dependency missing is `etcd`.
This PR injected a simple cloud-init script when creating instance to install `etcd` during node startup.
@andyzheng0831 for the cloud init script.
@wonderfly for the gci instance setup.
@pwittrock for the node e2e test change.

Return server's representation of pod from framework pod creation functions
Since PodInterface.Create returns the server's representation of the pod, which may differ from the api.Pod object passed to Create, we do the same from the framework's pod creation functions. This is useful if e.g. you create pods using Pod.GenerateName rather than Pod.Name, and you still want to refer to pods by name later on (e.g. for deletion).

Node E2E: Disable kubenet for local node e2e test.
After https://github.com/kubernetes/kubernetes/pull/28196, we must manually setup cni and nsenter in local node to run `make test_e2e_node`, which may not be necessary for local development.
I've tried to move cni downloading logic into `BeforeSuite`, however it is still hard to figure out who should install nsenter, manually installed by every developer? in the `setup_host.sh` script? in `BeforeSuite`?
This PR:
* Added a flag to disable kubenet and disabled kubenet in local test.
* Cleaned up the CNI installation logic a bit.

E2E: Add UpdatePod function in e2e framework and change the test to use it.

Some e2e tests need to update pod, but the pod update is a bit complex because of potential conflict. #28096 happened just because the test only called pod `Update` once.
This PR move the update pod logic into a util function `UpdatePod` in e2e framework, and change the tests to use it.

This also includes a simple script to do minor automatic updates to the CSV.
I'd like to get `update_owners.py` into a more usable state -- right now the CSV is based directly on the Google Sheets data. It has 9 outdated tests and is missing 80 new tests.
I can randomly assign new tests to people on kubernetes-maintainers, but are there any caveats to how the assignment should work? Should they be load balanced? Should some people in the group not receive issues? Etc.
