e2e test: Log container output on TestContainerOutput error
When a pod started with TestContainerOutput or TestContainerOutputRegexp
fails from unknown reason, we should log all output of all its containers
so we can analyze what went wrong.
This would help us to see what wrong in https://github.com/kubernetes/kubernetes/issues/40811 - a container is running there for 3 minutes and dies and we want to see what it did for these 3 minutes.

Implement automated downgrade testing.
Node version cannot be higher than the master version, so we must
switch the node version first. Also, we must use the upgrade script
from the appropriate version for GCE.

Create DefaultPodDeletionTimeout for e2e tests
In our e2e and e2e_node tests, we had a number of different timeouts for deletion.
Recent changes to the way deletion works (#41644, #41456) have resulted in some timeouts in e2e tests. #42661 was the most recent fix for this.
Most of these tests are not meant to test pod deletion latency, but rather just to clean up pods after a test is finished.
For this reason, we should change all these tests to use a standard, fairly high timeout for deletion.

Don't wait for the final deletion of pod
The final deletion of the pod depends on kubelet and other components operating correctly. The purpose of this e2e test is verifying the clientset can handle deleteOptions correctly, so waiting for the deletionTimestamp and deletionGraceperiod get set is good enough.
In the long run, we should move this set of e2e tests to integration tests.

add debugging to the client watch test
Adds debugging information for https://github.com/kubernetes/kubernetes/issues/42724. I suspect that the watch is closing early, but I'd like proof before I consider things like retrying the list and doing another watch to observe the delete. I'm not even sure that would satisfy the test
It seems like a flaky way to build the test. Why wouldn't we delete non-gracefully?

@wojtek-t saw you just hit this if you wanted to take a quick look at the debugging I added.

Add more e2e tests for DaemonSet templateGeneration and pod adoption

After some kubefed changes, the environment variable did not get propagated
and we defaulted back to 'federation' instead of
'e2e-federation'. This fixes ongoing service test issues in e2e.
This change allows validators to pass warnings as well as errors. This
was needed because of how support for docker 1.13+ and the new EE and CE
versions is currently being handled.

[Federation] Use and return created replicaset instead of the passed object.
Passed replicaset object doesn't contain object name, but has a prefix set in `GenerateName`. However, we need to operate on the object name later to uniquely identified the created object. So we need the created object with the name set by the API server.

New e2e node test suite with memcg turned on
The flag --experimental-kernal-memcg-notification was initially added to allow disabling an eviction feature which used memcg notifications to make memory evictions more reactive.
As documented in #37853, memcg notifications increased the likelihood of encountering soft lockups, especially on CVM.
This feature would valuable to turn on, at least for GCI, since soft lockup issues were less prevalent on GCI and appeared (at the time) to be unrelated to memcg notifications.
In the interest of caution, I would like to monitor serial tests on GCI with --experimental-kernal-memcg-notification=true.

[Fix Flaky Tests] E2e Node Flaky test suite runs serially
The [e2e Node Flaky Test Suite](https://k8s-testgrid.appspot.com/google-node#kubelet-flaky-gce-e2e&width=20) has been failing with strange errors.
This is because the tests in that suite are meant to be run serially, but are running in parallel, since that was left out of the config. This PR fixes this by changing the Flaky test suite to serial

[Bug Fix] Garbage Collect Node e2e Failing
This node e2e test uses its own deletion timeout (1 minute) instead of the default (3 minutes).
#41644 likely increased time for deletion. See that PR for analysis on that.
There may be other problems with this test, but those are difficult to pick apart from hitting this low timeout.
This PR changes the Garbage Collector test to use the default timeout. This should allow us to discern if there are any actual bugs to fix.

Create "framework" per upgrade test
There were already a few tests just using the default framework
namespace instead of creating a new one. Also there are several
testing libraries that use the default framework's default namespace
as well. It's just easier this way.
