rclpy: Change the output format of the default logger (RcutilsLogger)

edit

My log messages look like:

[INFO] [1605205588.116214862] [path_to_node.subsystem_name.node_name]: Here is a log message

The bit before the actual message takes up too much horizontal space, making it hard to read in my console (I'm using terminator, and have other consoles within it). I have already tried reducing the font size, but it still rarely fits on one line.

Could I change it so it is more like:

[INFO] [node_name]: Here is a log message

Or even:

[INFO]: Here is a log message

As often I do not care where the log message has come from.

Thanks!
