leading to failures using the kubernetes Go client API.
Failure:

Script to cache metadata requests on the jenkins master
Fixes https://github.com/kubernetes/kubernetes/issues/23545
Create an http server which caches most requests to the metadata server. Use special logic to cache access tokens such that the expires_on json field is correct. Add a script to simplify enabling/disabling the cache by editing `/etc/hosts`

Collect and expose runtime's image storage usage via Kubelet's /stats/summary endpoint
This information is useful to users since docker images are typically not stored on the root filesystem.
Kubelet will also consume this feature in the future to decide is evicting images will help with disk usage on the nodes.

Move internal types of job from pkg/apis/extensions to pkg/apis/batch
This addressed the job part of #23216, this is still WIP. Will notify once finished. I'd like to have it in before starting working on ScheduledJob.

Use kube-system namespace
Fixes#23153.
Sadly, kube-system isn't automatically created, so people need to make
sure to create it in their turnup scripts. Also after creating
kube-system it can take 10+ seconds for master and proxy to show up.
I tested the equivalent of these changes locally, but not these changes
themselves as I don't have a dev/build env up, so please read carefully
and maybe try them out!

use single writer to improve quota performance
Performance improvement is comparable to https://github.com/openshift/origin/pull/6658, though I'm getting some crazy stalls during initial calculation on master (not on this branch), so there may be an existing problem. This implementation won't scale out quite as well, but I don't think we'll need much more for a while and this one is easier to read.
This buckets based on namespace, then bunches updates where possible to avoid request fanout, and does fast notification when it can. It correctly handles updating multiple quota docs.

Make detect-node-names less brittle for G{C,K}E
Use the `--format='value()'` option with `gcloud compute instance-groups managed list{,-instances}` instead of `--format=yaml` with a series of `grep`s and `cut`s. This is hopefully a bit more stable.
Fixes#24120.

This was lost in a rebase in #24496 and, while not required to build, is

rkt: Return `FinishedAt` for pod
This is implemented via touching a file on stop as a hook in the systemd
unit. The ctime of this file is then used to get the `finishedAt` time
in the future.
In addition, this changes the `startedAt` and `createdAt` to use the api
server's results rather than the annotations it previously used.
It's possible we might want to move this into the api in the future.
Fixes#23887
I did the following manual testing:
```
$ cat ./examples/output/exit-output.yml
apiVersion: v1
kind: Pod
metadata:
labels:
name: exit
name: exit-output
spec:
restartPolicy: Never
containers:
- name: exit
image: busybox
command: ["sh", "-c", "echo Exiting in 60; sleep 60; echo goodbye"]
$ kubectl create -f ./examples/exit/exit-output.yaml
$ # wait
$ kubectl describe pod exit-output | grep State -A 4
State: Terminated
Reason: Completed
Exit Code: 0
Started: Tue, 19 Apr 2016 13:23:13 -0700
Finished: Tue, 19 Apr 2016 13:24:13 -0700
$ kubectl logs exit-output
Exiting in 60
goodbye
```
I double checked as well that the file at `/var/lib/kubelet/pods/$id/finished-$id` existed and looked as expected.

let admission plugins indicate they want nothing
An admission plugin can return `nil, nil` for construction. This is useful for dealing with cases where the `config` passed to you effectively means, "no work". The calling code already handles this.
