[feature] Support Debugging ROS2 Launch Files

[polyhobbyist]

what is needed
Launch files in ROS2 are Python scripts which execute parameterized ROS2 nodes. Additionally, ROS2 lifecycle nodes are maintained by the launch solution.

why is it needed
As these grow in complexity, they need to be debugged.

ROS2 python launch files are probably the most difficult source files in ROS2 to debug. First, there’s a lot going on when you started them including other nodes and associated source. Secondly, there’s almost no well-understood way to debug them including prints, pdb, and gdb. +1
