Add json,yaml output format support to kubectl create, kubectl apply
Fixes: https://github.com/kubernetes/kubernetes/issues/37390
**Release note**:
```release-note
Added support for printing in all supported `--output` formats to `kubectl create ...` and `kubectl apply ...`
```
This patch adds the ability to specify an output format other than
"name" to `kubectl create ...`. It can be used in conjunction with the
`--dry-run` option. Converts unstructured objects into known types in
order to support all `--output` values.
The patch prints `*resource.Info`s returned by the server. If a resource does not yet exist (and the `--dry-run` option is not set), the resource is created and printed in the specified format.

Update New Relic sample docs with dynamic hostname info
This PR shows how to set extra environment variables for the New Relic DaemonSet that can be generated at runtime. I'm using this technique to prepend cluster names to host names as they are reported to New Relic.

Add a build rule for the boilerplate unit test.
We recently added unit tests that just run whenever you run `hack/verify_boilerplate.sh`, which really isn't the right time to do that. This adds a build rule instead.

Makefile speedup on generated code
This has been languishing in a branch for a long time. It makes the build more consistent wrt GOPATH (I still hope to enforce GOPATH at some point) and it removes a `go list` from each codegen.
I verified manually that the files that this emits as part of the make are only change in safe ways (ordering, _test files removed, etc).

genericapiserver: extract CA cert from server cert and SNI cert chains
Without this PR a matching server cert or SNI cert is directly used as CA cert in the loopback client config. This fails if the cert is no CA cert.
With this PR the loopback client setup code walks through the chains of the server cert and the SNI certs to find a `CA:TRUE` cert. This is then used as the CA in the loopback client config.

Endpoints with TolerateUnready annotation, should list Pods in state terminating
**What this PR does / why we need it**:
We are using preStop lifecycle hooks to gracefully remove a node from a cluster. This hook is potentially long running and after the preStop hook is fired, the DNS resolution of the soon to be stopped Pod is failing, which causes a failure there.
**Special notes for your reviewer**:
Would be great to backport that to 1.4, 1.3
**Release note**:
```release-note
Endpoints, that tolerate unready Pods, are now listing Pods in state Terminating as well
```

Improve error reporting in Ceph RBD provisioner.
- We should report an error when user references a secret that cannot be found
- We should report output of rbd create/delete commands, logging "exit code 1"
is not enough.

--------- -------- ----- ---- ------------- -------- ------ -------
33m 33m 1 {persistentvolume-controller } Warning ProvisioningFailed Failed to provision volume with StorageClass "cephrbdprovisioner": rbd: create volume failed, err: exit status 1

retry RBAC initialization for up to 30 seconds, kill server on failure
RBAC initialization needs to complete in order to bootstrap a cluster. When the bootstrapping fails (etcd not ready has happened in e2e runs), things fail badly and we don't even kill the API server to force it to retry. This retries for up to 30 seconds and kills the server if it never succeeds.

Try parse golang logs by default
Glog by default logs to stderr, so Stackdriver Logging shows them all as errors. This PR makes fluentd try to parse messages using glog format and if succeeded, set timestamp and severity accordingly.

Ensure that assumed pod won't be expired until the end of binding
In case if api server is overloaded and will reply with 429 too many requests error, binding may take longer than ttl of scheduler cache for assumed pods 1199d42210/pkg/client/restclient/request.go (L787-L850)
This problem was mitigated by using this fix e4d215d508 and increased rate limit for api server. But it is possible that it will occur again.
In such cases when api server is overloaded and returns a lot of
429 (too many requests) errors - binding may take a lot of time
to succeed due to retry policy implemented in rest client.
In such events cache ttl for assumed pods wasn't big enough.
In order to minimize probability of such errors ttl for assumed pods
will be counted from the time when binding for particular pod is finished
(either with error or success)

Update Google API dependencies
In order to experiment with alpha or beta GCP APIs (that are new), we need to make the client compatible with v1 client. And there were some cosmetic changes that make them incompatible with the version that we were using before (e.g. passing pointers vs non-pointers in gensupport functions).
drop SetNodeStatus() Since it is never called now. klet.defaultNodeStatusFuncs() is set to klet.setNodeStatusFuncs now and setNodeStatus() function is called by other functions.

Add work queues to PV controller
PV controller should not use Controller.Requeue, as as it is not available in
shared informers. We need to implement our own work queues instead, where we
can enqueue volumes/claims as we want.
