Config does not create intermediate directories

[Austin Raney]

@dtarb found an issue while testing the software deployed on CUAHSI's JupyterHub instance. In short HS resources were not downloading. Upon inspection of the logs, during JupyterLab's plug-in registry phase, hydroshare_on_jupyter was failing to load because it could not create an intermediate directory for logging.

see source

# in ConfigFile class
       if path.is_file():
            raise FileNotDirectoryError(
                f"Configuration path: {str(path)} is a file not a directory."
            )
        elif not path.exists():
            path.mkdir()
        return path

Due to the crash, the ConfigFile's data_path property was not set. Therefore, when @dtarb tried to download a resource using the software, the software had no idea where to store it.
