        Tools have their own way of being configured from configuration files
        on the current path - for example, a .pep8rc file. Prospector will use
        its own configuration settings unless this method discovers some
        tool-specific configuration that should be used instead.

        :return: A tuple: the first element is a string indicating how or where
                 this tool was configured from. For example, this can be a path
                 to the .pylintrc file used, if used. None means that prospector
                 defaults were used. The second element should be an iterable of
                 Message objects representing any issues which were found when
                 trying to load configuration - for example, bad values in a
                 .pylintrc file. It is also possible to simply return None if
                 neither value is useful.
