End-user friendly description of the problem this fixes or functionality this introduces.
When users use OpenHands for production environments, the logs cannot be scrolled, which can cause the log files to become larger. By using TimedRotatingFileHandler, logs can be stored on a daily basis, making it easier to troubleshoot logs based on conversation time. By default, logs are saved for 7 days and will not cause the log files to become larger
