[Federation][kubefed]: Use StorageClassName for etcd pvc

This PR updates kubefed to use the StorageClassName field [added in 1.6](http://blog.kubernetes.io/2017/03/dynamic-provisioning-and-storage-classes-kubernetes.html
) for etcd's pvc to allow the user to specify which storage class they want to use.  If no value is provided to ``kubefed init``, the field will not be set, and initialization of the pvc may fail on a cluster without a default storage class configured.

The alpha annotation that was previously used (``volume.alpha.kubernetes.io/storage-class``) was deprecated as of 1.4 according to the following blog post:

http://blog.kubernetes.io/2016/10/dynamic-provisioning-and-storage-in-kubernetes.html

**Release note**:

```
'kubefed init' has been updated to support specification of the storage class (via --etcd-pv-storage-class) for the Persistent Volume Claim (PVC) used for etcd storage.  If --etcd-pv-storage-class is not specified, the default storage class configured for the cluster will be used.
```

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

  1. 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.
