Some incorrect Dockerfiles for testing

invalid-json-json-inside-string-double.Dockerfile

CMD '["echo", "Well, JSON in a string is JSON too?"]'

invalid-json-json-inside-string.Dockerfile

CMD "[\"echo\", \"Phew, I just managed to escaped those double quotes\"]"

invalid-json-single-quotes.Dockerfile

CMD ['echo','single quotes are invalid JSON']

invalid-json-unterminated-bracket.Dockerfile

CMD ["echo", "Please, close the brackets when you're done"

invalid-json-unterminated-string.Dockerfile

CMD ["echo", "look ma, no quote!]

As discussed here; https://github.com/docker/docker/pull/7461/files

Not really sure if parsing the JSON itself is something that needs testing (as it is core functionality of Go), but how to handle the errors, i.e. what kind of feedback is given back to the user might be worth describing :)
