update taints e2e, restrict taints operation with key, effect
Since taints are now unique by key, effect on a node, this PR is to restrict existing taints adding/removing/updating operations in taints e2e.

Log pressure condition, memory usage, events in memory eviction test
I want to log this to help us debug some of the latest memory eviction test flakes, where we are seeing burstable "fail" before the besteffort. I saw (in the logs) attempts by the eviction manager to evict besteffort a while before burstable phase changed to "Failed", but the besteffort's phase appeared to remain "Running". I want to see the pressure condition interleaved with the pod phases to get a sense of the eviction manager's knowledge vs. pod phase.

Plumb --feature-gates from TEST_ARGS to components in node e2e tests
This means you can set `TEST_ARGS` on the command line, in a `.properties` config for a Jenkins job, etc, to toggle gated features. For example:
`TEST_ARGS='--feature-gates=DynamicKubeletConfig=true'`

Networking test rewrite
Decomposes the old kubeproxy tests into (tcp, udp) tests for each of the following:
* intra-pod
* node-pod
* pod-Service
* node-Service
* endpoint-Service
* delete endpoints, confirm unreachability
* delete nodeport, confirm unreachability
* kube-proxy /proxymode, /healthz
Also gets rid of the old network conformance test that used apiserver proxy to check reported peer count of a webserver in a container (the netexec pod used in this test does the same thing without apiserver proxy).
Fixes https://github.com/kubernetes/kubernetes/issues/26490, https://github.com/kubernetes/kubernetes/issues/14204
[Feature:...] tag is recognized by most e2e suites and will prevent
test from being run in suites where it should not. This pattern is
used by other alpha feature tests.

federated ingress e2e - retry reads properly
@quinton-hoole I made this rookie mistake when I wrote the code and missed your comment in last PR.
- Corrected the reference of constant test/e2e/federated-ingress.go
- Move federation ingress query call to wait. PollImmediate()
- set private method to non-capital

Use federated namespace instead of the bootstrap cluster's namespace in Ingress e2e tests.
This should fix#31825.

Move StorageClass to a storage group
We discussed the pros and cons in sig-api-machinery yesterday. Choosing a particular group name means that clients (including our internal code) require less work and re-swizzling to handle promotions between versions. Even if you choose a group you end up not liking, the amount of work remains the same as the incubator work case: you move the affected kind, resource, and storage.
This moves the `StorageClass` type to the `storage.k8s.io` group (named for consistency with authentication, authorization, rbac, and imagepolicy). There are two commits, one for manaul changes and one for generated code.

Add e2e tests for eviction subresource.
This branch includes changes pending in both #31638 and #31721. I will rebase
once those merge.
Job controller synchronizes objects only when job itself or underlying pod
changes. Or, when full resync is performed once 10 mins. This leads e2e test
to unnecessarily wait that longer timeout, sometimes at least. I've added job
modification action which triggers resync, if the job wasn't terminated within
shorter period of time.

Add e2e test for Source IP preservation (pod to service cluster IP)
Working on #27134.
This PR added the e2e test for source ip preservation (pod to service cluster IP) in service.go. Test scenario described as below:
- Pick two different nodes in cluster.
- Create a clusterIP type service.
- Create an echo server, which echoes back client IP, to be part of the service.
- Create a client on another node. Hit the server through service cluster IP.
- Verify the source IP.

This gives the node e2e test binary a --feature-gates flag that populates a
FeatureGates field on the test context. The value of this field is forwarded
to the kubelet's --feature-gates flag and is also used to populate the global
DefaultFeatureGate object so that statically-linked components see the same
feature gate settings as provided via the flag.
This means that you can set feature gates via the TEST_ARGS environment
variable when running node e2e tests. For example:
TEST_ARGS='--feature-gates=DynamicKubeletConfig=true'

Delete the broken Celery+RabbitMQ example
The celery container used in the example is broken and does not come up
on most distros. The e2e test that was validating this example was not
detecting the fact the celery pod was crash looping.
I attempted to fix the celery container, but it proved to be tedious.
The proposed fix is to update the glibc version to >= 2.23. In this case
it requires updating the python docker image and the celery base image.
https://github.com/kubernetes/kubernetes/issues/31456
has more details.
I'm deleting the example instead of marking it as broken because a user
might overlook the broken warning and it should be trivial to revert
this PR if someone can fix the celery container.

Most of the contents of docs/ has moved to kubernetes.github.io.
Development of the docs and accompanying files has continued there, making
the copies in this repo stale. I've removed everything but the .md files
which remain to redirect old links. The .yaml config files in the docs
were used by some tests, these have been moved to test/fixtures/doc-yaml,
and can remain there to be used by tests or other purposes.
