Python logging by default sends all output to stderr, but that's not what normal programs usually do and is not expected for these scripts. Change the ubuntutools.getLogger() method to return a logger with handlers correctly set up to send INFO level (or lower) logs to stdout and WARNING level (or higher; technically INFO+1 level or higher) logs to stderr. This results in normally logged output going to stdout and warnings/errors going to stderr, as expected.
