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.

Add Persistent Volume E2E in the context of a disrupted kubelet
This PR adds a test suite for persistent volumes affected by a disrupted kubelet. Two cases are presented:
1. A volume mounted via PVC remains accessible after a kubelet restart.
2. When a pod is deleted while the kubelet is down, the mounted volume is unmounted successfully.
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

Recycle Pod Template Check
The kube-controller-manager has two command line arguments (--pv-recycler-pod-template-filepath-hostpath and --pv-recycler-pod-template-filepath-nfs) that specify a recycle pod template. The recycle pod template may not contain the volume that shall be recycled.
A check is added to make sure that the recycle pod template contains at least a volume.
