Logging.debug doesn't log

[Armandpl]

in scripts/train.py we set the logger level to e.g debug, in furuta_real we use logging.debug. The messages are not logged because when we set the logging level we set it on a logger object, so if we call logging.debug and not logger.debug we don't get the messages. In think logging provides a way to access instantiated loggers, we should use that instead
