retry on conflict simple example imeplementation

So far:

I hope this is along the lines of what is expected.

Adds:

• simple display of retry on conflict. The current code will produce the following log

  dhitt@local retry-on-conflict (retry-on-conflict %)]$ go run main.go 
  Successfully updated ConfigMap
  Operation cannot be fulfilled on configmaps "foobar": the object has been modified; please apply your changes to the latest version and try again
  Successfully updated ConfigMap

  Successfully updated ConfigMap
  Operation cannot be fulfilled on configmaps "foobar": the object has been modified; please apply your changes to the latest version and try again

I will add documentation on real world use cases/the nuances of the example in the readme. I will also be adding some docs about the function retryOnConflict itself and it's nuances.

cheers
