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.

rkt: Pass through os argument
This was lost in a rebase in #24496 and, while not required to build, is
required to function correctly under rkt (else panics!)

Incorrect attribute - docs - pod-security-context
Pod definition had incorrect spelling on attribute `securityContext`
Also fixed the flow of Motivation introduction paragraph.

Photon Controller is an open-source cloud management platform. More
information is available at:
http://vmware.github.io/photon-controller/
This commit provides initial support for Photon Controller. The
following features are tested and working:
- kube-up and kube-down
- Basic pod and service management
- Networking within the Kubernetes cluster
- UI and DNS addons
It has been tested with a Kubernetes cluster of up to 10
nodes. Further work on scaling is planned for the near future.
Internally we have implemented continuous integration testing and will
run it multiple times per day against the Kubernetes master branch
once this is integrated so we can quickly react to problems.
A few things have not yet been implemented, but are planned:
- Support for kube-push
- Support for test-build-release, test-setup, test-teardown
Assuming this is accepted for inclusion, we will write documentation
for the kubernetes.io site.
We have included a script to help users configure Photon Controller
for use with Kubernetes. While not required, it will help some
users get started more quickly. It will be documented.
We are aware of the kube-deploy efforts and will track them and
support them as appropriate.
Docker has removed the ParseRepositoryTag() function in
leading to failures using the kubernetes Go client API.
Lets use github.com/docker/distribution reference.ParseNamed()
instead.
Failure:

Refactor image related functions to use docker engine-api

Hopes can do some help, cc @Random-Liu
If it's ok, will add more work here.

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.
