Updated README to include client-go<->controller diagram
The sample-controller makes extensive use of various mechanisms
available in client-go. For writing custom controllers/operators
it will be helpful if there is precise description of how the
client-go library works and how/where it interfaces with
custom controller code.
Recently we published a blog post with these details here:
https://medium.com/@cloudark/kubernetes-custom-controllers-b6c7d0668fdf
This patch includes the diagram from the post, as was recommended
by @sttts on https://github.com/kubernetes/sample-controller/issues/13
