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.
Fix#42724#42646

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.

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.

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][e2e] Increase timeout waiting for service shard to appear
Most of recent federation service tests are failing with timeouts. although some times they do pass, giving kind of flaky nature. So increasing the timeout waiting for service shard to appear in federated cluster from 1 min to 5 mins.

[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

as well. It's just easier this way.

deflake TestPatch by waiting for cache
Fixes#39471
Rather than retry on conflicts for an unknown number of times, we have the resource version after the previous patch and we can use that to wait for a GET response that is at least as current as that resourceVersion.

Pods pending due to insufficient OIR should get scheduled once sufficient OIR becomes available (e2e disabled).
#41870 was reverted because it introduced an e2e test flake. This is the same code with the e2e for OIR disabled again.
We can attempt to enable the e2e test cases one-by-one in follow-up PRs, but it would be preferable to get the main fix merged in time for 1.6 since OIR is broken on master (see #41861).

[Federation][e2e] Add wait for namespaces to appear in federated cluster
Some federation e2e tests are failing because the namespace (created for every test case) does not seem to appear in one (or more) of federated clusters.
This may be a timing issue, so introducing a wait until the namespace is created in federated clusters.

cgroup names created by kubelet should be lowercased
**What this PR does / why we need it**:
This PR modifies the kubelet to create cgroupfs names that are lowercased. This better aligns us with the naming convention for cgroups v2 and other cgroup managers in ecosystem (docker, systemd, etc.)
See: https://www.kernel.org/doc/Documentation/cgroup-v2.txt
"2-6-2. Avoid Name Collisions"
**Special notes for your reviewer**:

**Release note**:
```release-note
kubelet created cgroups follow lowercase naming conventions
