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

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.

Kubelet: add image ref to ImageService interfaces
This PR adds image ref (digest or ID, depending on runtime) to PullImage result, and pass image ref in CreateContainer instead of image name. It also
* Adds image ref to CRI's PullImageResponse
* Updates related image puller
* Updates related testing utilities
~~One remaining issue is: it breaks some e2e tests because they [checks image repoTags](https://github.com/kubernetes/kubernetes/blob/master/test/e2e/framework/util.go#L1941) while docker always returns digest in this PR. Should we update e2e test or continue to return repoTags in `containerStatuses.image`?~~
Fixes#38833.
previously the formatting was broken for labels.Parse() function. I
fixed the spacing so it will format correctly for the generated go docs.
There was also a dangling "]" at the end of the first line so i deleted
it.
