implements StatefulSet update
**What this PR does / why we need it**:
1. Implements rolling update for StatefulSets
2. Implements controller history for StatefulSets.
3. Makes StatefulSet status reporting consistent with DaemonSet and ReplicaSet.
https://github.com/kubernetes/features/issues/188
**Special notes for your reviewer**:
**Release note**:
```release-note
Implements rolling update for StatefulSets. Updates can be performed using the RollingUpdate, Paritioned, or OnDelete strategies. OnDelete implements the manual behavior from 1.6. status now tracks
replicas, readyReplicas, currentReplicas, and updatedReplicas. The semantics of replicas is now consistent with DaemonSet and ReplicaSet, and readyReplicas has the semantics that replicas did prior to this release.

Fixed ResourceConsumer.CleanUp to properly clean up non-replication-controller resources and pods

federation: Add admission controller for policy-based placement
@nikhiljindal
Here's the initial version of the scheduling policy admission controller. It's at the point where it would benefit from having another pair of eyes look at it. The main thing I'm unsure of is the serialization of Kube resources for the webhook/query call.
Release Note:
```
The federation-apiserver now supports a SchedulingPolicy admission controller that enables policy-based control over placement of federated resources.

Get command uses print-column extn from Openapi schema
**What this PR does / why we need it**:
Kubectl Get command now uses metadata 'x-kubernetes-print-column' from Openapi schema to display a resource. This is to enable richer experience for non-compiled types (like service catalog API resources) in Kubectl. This functionality is currently guarded by a boolean flag "use-openapi-print-columns".

**Special notes for your reviewer**:
**Release note**:
```release-note
Get command uses OpenAPI schema to enhance display for a resource if run with flag 'use-openapi-print-columns'.

Fix etcd storage location for CRs
Fixes https://github.com/kubernetes/kubernetes/issues/46031
The first commit is easy, the second commit is hard.
@sttts Read the second commit very carefully and search the repo to make sure that you agree this is only affecting aggregator and apiextensions.
@pmorie @derekwaynecarr make sure you check to see if service catalog is double prefixing. Looks like we missed it in 1.6, but no one was using it.

Don't parse human-readable output from gcloud in tests
This is the reason `[k8s.io] Services should be able to change the type and ports of a service [Slow]` is currently failing on GKE e2e tests. For GKE jobs we run a prerelease version of gcloud, in which the default command output was changed.
gcloud's default output for commands is human readable, and is subject to change. Anything scripting against gcloud should always pass `--format=json|yaml|value(...)` so you get standardized output.

Scheduler should not log an error when there is no fit

kubeadm: improve quickstart instructions
**What this PR does / why we need it**:
Improves instructional output following setup of a kubernetes master with kubeadm.
This helps prevent unnecessary support overhead such as: https://github.com/kubernetes/kubeadm/issues/212#issuecomment-292015402
**Example current output**:
```
To start using your cluster, you need to run (as a regular user):
sudo cp /etc/kubernetes/admin.conf $HOME/
sudo chown $(id -u):$(id -g) $HOME/admin.conf
export KUBECONFIG=$HOME/admin.conf
```
**Example new output**:
```
To start using your cluster, you need to run (as a regular user):
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
```
**Release note**:
```release-note

Write audit policy file for GCE/GKE configuration
Setup the audit policy configuration for GCE & GKE. Here is the high level summary of the policy:
- Default logging everything at `Metadata`
- Known write APIs default to `RequestResponse`
- Known read-only APIs default to `Request`
- Except secrets & configmaps are logged at `Metadata`
- Don't log events
- Don't log `/version`, swagger or healthchecks
In addition to the above, I spent time analyzing the noisiest lines in the audit log from a cluster that soaked for 24 hours (and ran a batch of e2e tests). Of those top requests, those that were identified as low-risk (all read-only, except update kube-system endpoints by controllers) are dropped.
I suspect we'll want to tweak this a bit more once we've had a time to soak it on some real clusters.
