Acceptance flow - csv import

This fails Rubocop right now but I wanted to put it up so you can see the code and get an idea of how it works.
Ok, now that I see what this does, I realize its solely for testing the import without having to create the users ahead of time.  I think we want to prevent this from happening in production.  Can you add code that only allows this to run in staging? (don't forget that the ruby env var is still set to production on staging)
