Fix DeletingLoadBalancer event generation.
release-note:
```release-note
Fix DeletingLoadBalancer event generation.
```
Also patch up a log statement to log the service's namespace and name
rather than potentially just logging `kind:"" apiVersion:""`.
It doesn't work as written because `service` is always nil on this line. If it wasn't, then we wouldn't have taken this branch. `deltaService` is what contains the info that we have about the service.
Example of how the event generation fails as currently written:
```
E0426 22:18:41.726835 10 event.go:257] Could not construct reference to: '&api.Service{TypeMeta:unversioned.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:api.ObjectMeta{Name:"", GenerateName:"", Namespace:"", SelfLink:"", UID:"", ResourceVersion:"", Generation:0, CreationTimestamp:unversioned.Time{Time:time.Time{sec:0, nsec:0, loc:(*time.Location)(nil)}}, DeletionTimestamp:(*unversioned.Time)(nil), DeletionGracePeriodSeconds:(*int64)(nil), Labels:map[string]string(nil), Annotations:map[string]string(nil)}, Spec:api.ServiceSpec{Type:"", Ports:[]api.ServicePort(nil), Selector:map[string]string(nil), ClusterIP:"", ExternalIPs:[]string(nil), LoadBalancerIP:"", SessionAffinity:""}, Status:api.ServiceStatus{LoadBalancer:api.LoadBalancerStatus{Ingress:[]api.LoadBalancerIngress(nil)}}}' due to: 'selfLink was empty, can't make reference'. Will not report event: 'Normal' 'DeletingLoadBalancer' 'Deleting load balancer'

add user.Info.GetExtra
I found myself wanting this field (or something like it), when trying to plumb the information about which scopes a particular token has.
Only the token authenticators have that information and I don't want tokens to leak past the authenticator. I thought about extending the `authenticator.Token` interface to include scopes (`[]string`), but that felt a little specific for what I wanted to do. I came up with this as an alternative.
It allows the token authenticator to fill in the information and authorizers already get handed the `user.Info`. It means that implementors can choose to tie the layers together if they wish, using whatever data they think is best.

reflect.Call is fairly expensive, performing 8 allocations and having to
set up a call stack. Using a fairly straightforward to generate switch
statement, we can bypass that early in conversion (as long as the
function takes responsibility for invocation). We may also be able to
avoid an allocation for the conversion scope, but not positive yet.

Fix use of docker removed ParseRepositoryTag() function
Docker has removed the ParseRepositoryTag() function in

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.

This has been supplanted by a) the DockerJSON.CreatedAt field and b) the
ContainerStatus.CreatedAt, where the first is used for creating the
second.
The `.Created` field was only written to as far as I can see.
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.

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.
