Move api helpers.go to a subpackage
Part of https://github.com/kubernetes/kubernetes/issues/44065.
This PR moves the pkg/api/helpers.go to its own subpackage. It's mostly a mechanic move, except that
* I removed ConversionError in helpers.go, it's not used by anyone
* I moved the 3 methods of Taint and Toleration to pkg/api/methods.go, and left a TODO saying refactoring these methods to functions.
I'll send a few more PRs to make the k8s.io/kubernetes/pkg/api package only contains the code we want in the k8s.io/api repo, then we can run a [script](a0015fd1be (diff-7a2fbb4371972350ee414c6b88aee1c8)) to cut the new repo.

Remove [Flaky] from presistent volume NFS tests.
**What this PR does / why we need it**:
PV e2e test flaked because of a lack of isolation of test objects (PVs, claims). The common symptoms being volume-mounting pods timing out or an unexpected number of unbound claims being detected.
PR #43645 Introduced the selector labels to test objects that restricted binds to within each "testspace". To accomplish this the test namespace was set as a label for all PVs and selector for all Claims. This allows each test to act as if it's isolated while still creating and binding PVs in parallel w/ other tests.
This has been tested in parallel on both 3-node gci and debian clusters as
`--ginkgo.focus="\[Volume\]" --ginkgo.skip="\[Disruptive\]|\[Feature.*\]|\[Serial\]"`
with out signs of flakiness.

make unstructured items correspond to other items for storage
"normal" `Items` elements include the struct itself, not a pointer to the struct. Some of the deeper bits of storage rely on this behavior in reflective paths.
This updates the `UnstructuredList` to be "normal".

Add a retry to cluster-autoscaler e2e
This should fix https://github.com/kubernetes/kubernetes/issues/44268.
The flake was caused by following sequence of events:
1. Cluster was at minimum size (3), some node was unneeded for a while.
2. Setup for some test (scale-down, failure) would increase node group size (to 5) and wait for new nodes to come up.
3. As soon as new node come up (cluster size 4) CA would scale-down the old unneeded node (setting node group size to 4).
4. Node group would not reach size 5 (as the target was now 4) and the test would timeout and fail.
This PR makes the setup monitor re-set the target node group size if the above scenario happens.

hack/cluster: download cfssl if not present
hack/local-up-cluster.sh uses cfssl to generate certificates and
will exit it cfssl is not already installed. But other cluster-up
mechanisms (GCE) that generate certs just download cfssl if not
present. Make local-up-cluster.sh do that too so users don't have
to bother installing it from somewhere.

federation: Fixing runtime-config support for federation-apiserver
Fixes https://github.com/kubernetes/kubernetes/issues/42587
Ref https://github.com/kubernetes/kubernetes/issues/38593
Fixing the broken `--runtime-config` flag support in federation-apiserver. Fixing the bugs and using it to disable batch and autoscaling groups. Users can enable them by passing `--runtime-config=apis/all=true` to federation-apiserver.
~This also includes a bug fix to kube-apiserver registry that allows users to disable api/v1 resources~

Add test for provisioning with storage class
This PR re-introduces e2e test for dynamic provisioning with storage classes.
It adds the same test as it was merged in PR #32485 with an extra patch adding region to AWS calls. It works well on my AWS setup, however I'm using shared company account and I can't run kube-up.sh and run the tests in the "official" way.
@zmerlynn, can you please try to run tests that led to #34961?
@justinsb, you're my AWS guru, would there be a way how to introduce fully initialized AWS cloud provider into e2e test framework? It would simplify everything. GCE has it there, but it's easier to initialize, I guess. See https://github.com/kubernetes/kubernetes/blob/master/test/e2e/pd.go#L486 for example - IMO tests should not talk to AWS directly.

[Federation] Cleanup e2e framework
This PR is intended to simplify maintenance of the federation e2e tests:
- refactor cluster helpers into framework so they can be reused by upgrade tests
- remove unused functions
- move backend pod management to the tests that require it rather than relying on the common cluster object
- use a slice instead of a map to manage cluster objects to make it simpler for tests that need it to find the primary cluster themselves
Commit ``fed: Refactor e2e cluster functions into framework for reuse`` was originally included in #43500, but is included here because it formed the basis for this cleanup.

Fix pv upgrade test failure
**What this PR does / why we need it**:
2 changes were made that broke the pv upgrade test:
1. MakePod() was changed so that the volume mount point is at /mnt/volume<n> instead of /mnt. This change updates the path that the pod writes to.
2. The MakePod() call was changed to CreatePod(), which creates the pod and expects a long running pod. But the upgrade test uses a short running pod, and the call to TestContainerOutput() will also create the pod. This changes it back to MakePod()

[Federation] Add integration test for secrets
This PR adds an integration test for secrets that:
- performs create/read/update/delete on federation resources and validates that the changes are propagated to member clusters.
- uses an abstraction layer (fixture and adapter) to minimize the code required to support each federated type
- It should be possible to replace a test-specific adapter with a runtime adapter in the future (as per #41050)
- reuses fixture (federation api and clusters) across different resource types to minimize setup overhead
- on a fast machine, setup takes ~4s, and validating each type takes ~2s
- uses the [Subtest feature added in Go 1.7](https://blog.golang.org/subtests) to allow the test for a specific controller to be run in isolation
- ``make test-integration WHAT="federation -test.run=TestFederationCRUD/secret"``
Once this PR merges the test can be extended to target other federated types.
This PR targets #40705
