Added workflows, badges and repos file for ROS Iron

[fmauch]

Since ros2_control is also released for iron, it would make sense to add workflows for iron. Now that industrial-ci is available for iron, as well, there should be nothing blocking this anymore.

This PR assumes there will be an iron branch (which would probably be pointing towards master atm). If this is not desired and iron should be built from master, the PR will have to be adapted.

Thanks a lot and indeed for the next few weeks we probably won't branch for Iron.

[fmauch]

Alright, then I'll update this accordingly.

@bmagyar updated the PR to not expect an iron branch.

Updated author information, as I had setup my container wrong.
