Cli tools documentation
This Pull Request is a direct link to issue #550 which looks to improve documentation, specifically in CLI commands like tf2_echo. In this PR, all tools and documentation related to tf2_ros are put in one central place, hopefully https://docs.ros.org/.
I've recreated the rosdoc.yaml file in rosdoc2 terms so doxygen and sphinx content should be put out into the same file. As for the Links to the Doxygen content I have to rewrite those to be locally linked
This pull request has been mentioned on ROS Discourse. There might be relevant details there:

I made here some suggestions https://github.com/CursedRock17/geometry2/pull/1
I went ahead and added those changes you suggested, along with getting the Sphinx and Doxygen docs working for both python and C++
