Add file-content launch substitution #708

Closed cottsay closed 1 year ago

cottsay commented 1 year ago

This substitution implements a portable mechanism to read the contents of a file on disk. This procedure is used in various scenarios throughout ROS 2, and currently relies on exec and command substitutions to read files.

I'm particularly interested in review of the substitution name.

Reference implementation: ros2/demos#627

Closes #707
