Description
Description
Now that content filters are supported in rclpy (https://github.com/ros2/rclpy/pull/1506, https://github.com/ros2/rclpy/pull/1521), it would make a lot of sense to allow passing a content filter to ros2 topic echo|bw|hz.
Motivation
This could serve as a debugging tool for writing the content filters, and also as a practical tool printing/measuring only messages of interest.

Research direction
Start by reading the existing ros2 topic echo, bw, and hz command entry points and the linked rclpy content-filter support. Trace how each command accepts topic-related options and determine a consistent way to pass a content filter. Done means all three commands can apply the filter while retaining their current echoing or measurement behavior.
