Allow to disable a logger by name

Feature description

It would be nice to have a possibility to disable a certain logger completely from code. I have a c++ node which uses moveit internally. Moveit uses a lot of named loggers (e.g. moveit_robot_model.robot_model). As the logging information from some of these loggers is rather irrelevant and distracts from valuable information I would like to completely silence these loggers (at least from the console output) e.g. by calling something like:

rclcpp::get_logger("moveit_robot_model.robot_model").disable();

What I already tried was to set the logger level to Fatal or Error.

rclcpp::get_logger("moveit_robot_state.robot_model").set_level(rclcpp::Logger::Level::Fatal);

This didn't seem to work. (I would guess moveit sets the log level internally to something else, or there is some other magic happening?)

Start with the rclcpp::get_logger and Logger::set_level entry points mentioned in the issue, then trace how named logger levels affect console output. Define and test behavior for completely silencing one named logger, including the interaction with existing level changes; done means the requested logger can be disabled from code without suppressing unrelated loggers.
