Manual cherrypick of #65034 to 1.8: make json serializer case sensitive
fixes partially https://github.com/kubernetes/kubernetes/issues/64612
This PR imports the latest jsoniterator library so that case sensitivity during unmarshalling is optional. The PR also sets Kubernetes json serializer to be case sensitive.
**Release note**:
```release-note
ACTION REQUIRED: Kubernetes JSON deserializer is now case-sensitive to restore compatibility with pre-1.8 servers. If your config files contains fields with wrong case, the config files will be now invalid.

Kubernetes-commit: fa557ee7921fc8305d4978e66eb653c92ed1a7ce
This prevents a race condition where the sharedIndexInformer was
causeing the processorListener's run and pop method to be started
twice. That violated the SharedInformer's interface guarantee of
sequential delivery and also caused panics on shutdown.

Previously, the fake RESTClient in client-go required a Registry. It
used the Registry to fetch the GroupVersion for the fake client.
However, the way it did so was dubious in some cases (it hard-coded the
default API group in places), and not strictly necssary.
This updates the fake client to just recieve the GroupVersion and
internal group name directly, instead of requiring a Registry, so that
it can be consumed in unit tests where a Registry isn't necessarily
readily available (e.g. elsewhere in client-go).

update-staging-godeps: only mangle staging repos in staging Godeps.json
- this re-adds non-staging k8s.io/* repos to the staging Godeps.jsons
- x-outs instead of removing of staging dependencies in order to get a
precise trigger for a complete godep restore+save run in the publisher
bot.
The first breaks k8s.io/kube-aggregator's staging export.
The second potentially leads to inconsistent godeps in our exported staging repos.

Fix discovery restmapper finding resources in non-preferred versions
Fixes: #52219
Also reverts behavioral changes to tests that version-qualified cronjobs to work around this issue.
The discovery rest mapper was only populating the priority rest mapper's search list with preferred groupversions.
That meant that if a resource existed in multiple non-preferred versions, AND did not exist in the preferred version (like cronjob, which only exists in v1beta2.batch and v2alpha1.batch, but not v1.batch), the priority restmapper would not find it in its group/version priority list, and would return an error.
```release-note
Fixed an issue looking up cronjobs when they existed in more than one API version
```

Plumbing the proxy dialer to the webhook admission plugin
* Fixing https://github.com/kubernetes/kubernetes/issues/49987. Plumb the `Dial` function to the `transport.Config`
* Fixing https://github.com/kubernetes/kubernetes/issues/52366. Let the webhook admission plugin sets the `TLSConfg.ServerName`.
I tested it in my gke setup. I don't have time to implement an e2e test before 1.8 release. I think it's ok to add the test later, because *i)* the change only affects the alpha webhook admission feature, and *ii)* the webhook feature is unusable without the fix. That said, it's up to my reviewer to decide.
Filed https://github.com/kubernetes/kubernetes/issues/52368 for the missing e2e test.
( The second commit is https://github.com/kubernetes/kubernetes/pull/52372, which is just a cleanup of client configuration in e2e tests. It removed a function that marshalled the client config to json and then unmarshalled it. It is a prerequisite of this PR, because this PR added the `Dial` function to the config which is not json marshallable.)
```release-note
Fixed the webhook admission plugin so that it works even if the apiserver and the nodes are in two networks (e.g., in GKE).
Fixed the webhook admission plugin so that webhook author could use the DNS name of the service as the CommonName when generating the server cert for the webhook.
Action required:
Anyone who generated server cert for admission webhooks need to regenerate the cert. Previously, when generating server cert for the admission webhook, the CN value doesn't matter. Now you must set it to the DNS name of the webhook service, i.e., `<service.Name>.<service.Namespace>.svc`.

use specified discovery information if possible
Fixes https://github.com/kubernetes/kubernetes/issues/49948
This uses the available discovery information if available, but it seems we never updated "normal" resources to show the singular name, so its often not available. I've left this code compatible.
