    pass credentials via config file instead of magic

    Passing credentials via an assumed environment inheritance is bad
    form, and breaks under new tox. Honestly, we only really need 2 vars
    passed in, so we might as well make it a config file that we'll parse.

    Add a functional_creds.conf.sample for people to know what one should
    look like. Update README to explain it.
