Learn how to access the Kubernetes API from a Function

Hi, it's Alex, the OpenFaaS founder here. This post is by Han from our team, but I have written an in-depth intro that I hope you'll find interesting.

Here's a quick overview:

> We’ll show you how to access any part of the Kubernetes API or a Custom Resource using a ServiceAccount and granular permissions

> You’ll learn how you’re already using the Kubernetes API, what an Operator is, and why a Function may be a better fit some of the time. We’ve also included a code-example so you can get going with that today.
