+KEYFILE_NOT_FOUND_ERROR = 'ERROR: Oauth2 key file not found! Please specify ' \

PEP8 [1] recommends breaking long lines by implied continuation inside
parentheses instead of using backslashes when possible. What do you think about
following this and rewriting these constants like this:

    KEYFILE_NOT_FOUND_ERROR = (
        'ERROR: Oauth2 key file not found! Please specify '
        'it as an optional argument using -k or --key or '
        ...
    )
