Using rqt_console and rqt_logger_level to modify the logging level on the fly

ROS provides a series of tools to manage logging messages. In ROS Kinetic, we have two separate GUIs: rqt_logger_level to set the logging level of the nodes or named loggers and rqt_console to visualize, filter, and analyze the logging messages.
