7a573d4d3c Add test_list command, to enumerate unit and e2e tests. 
This uses go/parser and go/ast to analyze all test files in ~1 second.
It only recognizes a few simple structures that the tests all have, and
modifies a few tests to fit expected structure better.

This is part of an effort to ensure all tests have owners, by having a
verify check to catch new tests being added without an owner.

[e2e density test] Fix unnecessary Delete RC requests when not running latency test

As the following code block
https://github.com/kubernetes/kubernetes/blob/master/test/e2e/density.go#L666-L670
shows, after running each density test case, it will attempt to delete "additional replication controllers" even though there is **no additional replication controller**.

When we are not running latency test, API Server will return "404 error code". So, I propose to move the above code block inside thedetermine statementsif `itArg.runLatencyTest{ }` , looks like:

```
if itArg.runLatencyTest {
  ...
  for i := 1; i <= nodeCount; i++ {
    name := additionalPodsPrefix + "-" + strconv.Itoa(i)
    c.ReplicationControllers(ns).Delete(name, nil)
  }
}
```
In this way, removing RC will be executed only if we set `itArg.runLatencyTest` to be `true`. It can avoid post some necessary requests to API Server.

Issuse is #30977

[GarbageCollector] Fix kubectl rolling-update to work with GC

This changes the order of the [Rename()](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/rolling_updater.go#L532) function. After the change, Rename() first deletes the old RC and orphans its pods, then creates the new RC, which will then have a chance to adopt the orphaned pods.

This also fixes the "should support rolling-update to same image" [test](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/kubectl.go#L915) when the garbage collector is on.

Here is the detailed explanation on why the test would have failed:
`kubectl rolling-update` will [rename](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/rolling_updater.go#L532-L546) the RC. It first creates the an identical RC (including spec.selectors) with the new name, then it deletes the existing RC. When GC is turned on, the newly created RC cannot adopt the existing pod, because it has a controllerRef pointing to the exising RC, so the new RC will create new pods and expect to see the creation. However, the new RC and the old RC have the same selector, so sometimes the old RC, instead of the new RC, has its [expectation lowered](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/replication/replication_controller.go#L346-L362), the new RC's expectation will stuck forever. The e2e test then times out when executing `kubectl delete newRC`, because there is the new RC will not scale down as its expectation is not fulfilled.

A side-note, we should fix [rm.getPodController()](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/replication/replication_controller.go#L346) to respect pod's controllerref, that will prevent similar bugs.

Also note that an old version `kubectl rolling-update` will not work with the GC. We cannot fix that.

Revert revert of adding resource constraints for master components in density tests

The problem was the time when resource constraints were generated. It turns out that the provider is not set there. This version should work.

Automatic merge from submit-queue

Use pause image depending on the server's platform when testing

Removed all pause image constant strings, now the pause image is chosen by arch. Part of the effort of making e2e arch-agnostic.

The pause image name and version is also now only in two places, and it's documented to bump both
Also removed "amd64" constants in the code. Such constants should be replaced by `runtime.GOARCH` or by looking up the server platform

Fixes: #22876 and #15140
Makes it easier for: #25730
Related: #17981

This is for `v1.3`
