Install all Tier 1 RMWs in containers

[SteveMacenski]

Description

I'm looking to test code in a matrix with all Tier 1 RMWs. Currently only the default is installed so I can't simply change env in actions to use the one I desire. That seems easier than needing to compile each other RMW (e.g. cyclone) alongside the code every workflow by including it in a repos file since its not a strict package.xml dependency.

Completion Criteria

Update the docker containers to include all Tier 1 supported RMWs

Or -- analogously, have the default examples have the steps

    - name: Install Tier 1 DDS
      run: sudo apt install ros-iron-rmw-cyclonedds-cpp ... -y

In them so its immediately clear. Perhaps also explicitly set the env var too to make it clear to folks the workflow to get what they want out of the box without thinking.

#59 installs the other Tier 1 DDS implementation in the non-base Ubuntu images. I moved your suggestion to the action-ros-ci repo: ros-tooling/action-ros-ci#838
