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'.
An example command:
kubectl get pods --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.

@smarterclayton
The problem was that removing the requirement from the predicate resulted in not using "trigger" function in Cacher, which is super critical for performance. And this was messed up.

Scheduler should not log an error when there is no fit
**What this PR does / why we need it**:
The scheduler should not log an error when it is unable to find a fit for a pod as it's an expected situation when resources are unavailable on the cluster that satisfy the pods requirements.

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
NONE
```
Get command now uses metadata x-kubernetes-print-columns, if present, in Openapi schema
to format output for a resource. This functionality is guarded by a boolean
flag 'use-openapi-print-columns'.

handle unversioned objects for encoding for CRs
Fixes https://github.com/kubernetes/kubernetes/issues/47036
This updates the encoding for "special" types like `Status` when coming back through the CR APIs. It also closes a bug this allowed to be exposed in validation for CRs
xref: https://github.com/kubernetes/features/issues/95
Go's loop-clause variables are allocated once and the items are copied
to that variable while iterating through the loop. This means, these
variables can't escape the scope since closures are bound to loop-clause
variables whose value change during each iteration. Doing so would lead
to undesired behavior. For more on this topic see:
https://github.com/golang/go/wiki/CommonMistakes
So in order to workaround this problem in sync controller e2e tests, we
iterate through the map and copy the map value to a variable inside the
loop before using it in closures.
Fixes issue: #47059
This commit includes the following two changes:
* Move pre-test checks (pods/nodes ready) to BeforeEach() so that it's
clear whether the test has run or not.
* Dumping logs for unready pods.

add gzip compression to GET and LIST requests
Fixes https://github.com/kubernetes/kubernetes/issues/44164
Enable compressed response bodies for non-watch GET and LIST requests on API Objects.
**What this PR does / why we need it**: Adds compression via Accept-Encoding header, returns Content-Encoding header on responses (only supports gzip at this time). Enabled solely for GET and LIST requests which can return very large response bodies.
