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.

Admission plugin to merge pod and namespace tolerations for restricting pod placement on nodes
```release-note
This admission plugin checks for tolerations on the pod being admitted and its namespace, and verifies if there is any conflict. If there is no conflict, then it merges the pod's namespace tolerations with the the pod's tolerations and it verifies them against its namespace' whitelist of tolerations and returns. If a namespace does not have its default or whitelist tolerations specified, then cluster level default and whitelist is used. An example of its versioned config:
apiVersion: apiserver.k8s.io/v1alpha1
kind: AdmissionConfiguration
plugins:
- name: "PodTolerationRestriction"
configuration:
apiVersion: podtolerationrestriction.admission.k8s.io/v1alpha1
kind: Configuration
default:
- Key: key1
Value: value1
- Key: key2
Value: value2
whitelist:
- Key: key1
Value: value1
- Key: key2
Value: value2

Add dockershim only mode
This PR added a `experimental-dockershim` hidden flag in kubelet to run dockershim only.
We introduce this flag mainly for cri validation test. In the future we should compile dockershim into another binary.

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] Remove FEDERATIONS_DOMAIN_MAP references
Remove all references to FEDERATIONS_DOMAIN_MAP as this method is no longer is used and is replaced by adding federation domain map to kube-dns configmap.
cc @madhusudancs @kubernetes/sig-federation-pr-reviews
**Release note**:
```
[Federation] Mechanism of adding `federation domain maps` to kube-dns deployment via `--federations` flag is superseded by adding/updating `federations` key in `kube-system/kube-dns` configmap. If user is using kubefed tool to join cluster federation, adding federation domain maps to kube-dns is already taken care by `kubefed join` and does not need further action.

test/e2e_node: prepull images with CRI
Part of https://github.com/kubernetes/kubernetes/issues/40739
- This PR builds on top of #40525 (and contains one commit from #40525)
- The second commit contains a tiny change in the `Makefile`.
- Third commit is a patch to be able to prepull images using the CRI (as opposed to run `docker` to pull images which doesn't make sense if you're using CRI most of the times)
Marked WIP till #40525 makes its way into master

Per Clayton's suggestion, move stuff from cluster/lib/util.sh to
hack/lib/util.sh. Also consolidate ensure-temp-dir and use the
hack/lib/util.sh implementation rather than cluster/common.sh.
