Merge #161

161: Document missing ingress.className value in README.md r=alallema a=c0bra

# Pull Request

## What does this PR do?

The README.md is missing documentation of the `ingress.className` value.  If you mistakenly use an annotation like `kubernetes.io/ingress.class: nginx` you will get an error and scratch your head about how to address it.
