rkt: Add post-start hook support.
This adds a poll-and-timeout procedure after the pod is
started, to make sure the post-start hooks execute when the
container is actually running.
This is a temporal workaround for implementing post-hooks,
a long term solution is to use lifecycle event to trigger
those hooks, see https://github.com/kubernetes/kubernetes/issues/23084.
Also this fixes a bug of getting container ID for a non-running
container when running pre-stop hook.

Add kubelet flags for eviction threshold configuration
This PR just adds the flags for kubelet eviction and the associated generated code.
I am happy to tweak text, but we can also do that later at this point in the release.
Since this causes codegen, I wanted to stage this first.

Quota ignores pod compute resources on updates
Scenario:
1. define a quota Q that tracks memory and cpu
2. create pod P that uses memory=100Mi, cpu=100m
3. update pod P to use memory=50Mi,cpu=10m
Expected Results:
Step 3 should fail with validation error.
Quota Q should not have changed.
Actual Results:
Step 3 fails validation, but quota Q is decremented to have memory usage down 50Mi and cpu usage down 40m. This is because the quota was getting updated even though the pod was going to fail validation.
Fix:
Quota should only support modifying pod compute resources when pods themselves support modifying their compute resources.
This also fixes https://github.com/kubernetes/kubernetes/issues/24352
/cc @smarterclayton - this is what we discussed.

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.

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.
