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.

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:

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.

Use mCPU as CPU usage unit, add version in PerfData, and fix memory usage bug.
Partially addressed #24436.
This PR:
1) Change the CPU usage unit to "mCPU"
2) Add version in PerfData, and perfdash will only support the newest version now.
3) Fix stupid mistake when calculating the memory usage average.
