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.

Mark image as deliberately optional in v1 Container struct. Many objects in the Kubernetes API inherit the container struct and only Pods require the field to be set.

conversion-gen: make staging dirs independent of living in vendor/
The `+k8s:conversion-gen` tags included the package directory inside of kube's vendor dir. This
makes them invalid when we publish staging repos.
Without this PR our sample-apiserver example code-generation is broken once published.

k8s.io/code-generator: hide gen test output from go tools
The underscore in front of _test makes the go tools (including godep) to
ignore those packages by default. We do not want to create dependencies
to client-go and friends through the _test output.

Cronjob beta defaults
**What this PR does / why we need it**:
I forget to set the defaults in beta for (successful|failed)JobsHistoryLimit so doing this now. It's already too late for 1.8 so this goes into 1.9.
**Release note**:
```release-note
Set defaults for successfulJobsHistoryLimit (3) and failedJobsHistoryLimit (1) in batch/v1beta1.CronJobs
```
Remove the MonitorRequest method and replace with a method that takes
request.RequestInfo, which is our default way to talk about API objects.
Preserves existing semantics for calls.
Default http.ProxyFromEnvironment uses uppper case proxy
environment variables first, and if they are not defined,
tries lower case. For NewProxierWithNoProxyCIDR we should
provide similar user experience.

etcd3 store: retry with live object on conflict if there was a suggestion
Retry with a live object instead of the cached version if the watch
cache receives a conflict trying to do the update.
Fixes#41892
In GuaranteedUpdate, if it was called with a suggestion (e.g. via the
watch cache), and the suggested object is stale, perform a live lookup
and then retry the update.

Increase sliding window to 5hr for request_latencies metric
We're seeing high latency values for a couple of types of api calls in our density test (ref https://github.com/kubernetes/kubernetes/issues/51899). And we're recording values from only the last 1 hour in the metric (as @wojtek-t told me offline) - so our test result is pretty much counting only the calls during the delete phase.

Improve apiserver metrics reporting
Normalize "WATCHLIST" to "WATCH", add "scope" to the other metrics (listing 50k pods is != listing pods in a namespace), and add a new scope "resource" to cover individual resource calls.
This roughly aligns metrics with our ACL model (technically resource scope is GET, but POST to a subresource and POST to a namespace are not the same thing).
```release-note
WATCHLIST calls are now reported as WATCH verbs in prometheus for the apiserver_request_* series. A new "scope" label is added to all apiserver_request_* values that is either 'cluster', 'resource', or 'namespace' depending on which level the query is performed at.

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`.
```
