Polymorphic Scale Client

This PR introduces a polymorphic scale client based on discovery information that's able to scale scalable resources in arbitrary group-versions, as long as they present the scale subresource in their discovery information.

Currently, it supports `extensions/v1beta1.Scale` and `autoscaling/v1.Scale`, but supporting other versions of scale if/when we produce them should be fairly trivial.

It also updates the HPA to use this client, meaning the HPA will now work on any scalable resource, not just things in the `extensions/v1beta1` API group.

**Release note**:
```release-note
Introduces a polymorphic scale client, allowing HorizontalPodAutoscalers to properly function on scalable resources in any API group.
```

Cluster Federation

Kubernetes Cluster Federation enables users to federate multiple Kubernetes clusters. Please see the user guide and the admin guide for more details about setting up and using the Cluster Federation.

Building Kubernetes Cluster Federation

Please see the Kubernetes Development Guide for initial setup. Once you have the development environment setup as explained in that guide, you also need to install jq

Building cluster federation artifacts should be as simple as running:

make build

You can specify the docker registry to tag the image using the KUBE_REGISTRY environment variable. Please make sure that you use the same value in all the subsequent commands.

To push the built docker images to the registry, run:

make push

To initialize the deployment run:

(This pulls the installer images)

make init

To deploy the clusters and install the federation components, edit the ${KUBE_ROOT}/_output/federation/config.json file to describe your clusters and run:

make deploy

To turn down the federation components and tear down the clusters run:

make destroy

Ideas for improvement

Continue with destroy phase even in the face of errors.

The bash script sets set -e errexit which causes the script to exit at the very first error. This should be the default mode for deploying components but not for destroying/cleanup.
