Add smallest image possible to use for e2e-testing and getting started examples

The images we use in our Getting Started example, and more important to me, our end-to-end testing scripts are very large.  This makes testing our cluster's basic function really slow as each minion after provisioning has to download ~600 MB dockerfile/nginx images just to curl it and get a response.

I put together a simple image that when built is ~3MB in size that I would like us to publish on Docker Hub under the kubernetes namespace that we can use for getting started guides and the basic e2e test.

The image enables the end-user Getting Started examples to drastically reduce in total-time .
