    Add generate_passwords.py to generate passwords

    As with all tools, this is a first pass at the generation. Perhaps we
    even want to move this into kolla/kolla/cmd and be generated with tox
    itself in the future.

    This tool, when run, will only populate empty fields that have no
    values meaning that it is safe to run repeatedly on the same file.

    Of note, there is no way to preserve comments in the file after it has
    been processed by the yaml parser in python. Comments and sections
    will remain in the passwords.yml template for additional documentation
    if the user wishes to populate the file themselves.

    Use SystemRandom and clean up the docs a bit to not use pronouns.
