Release Autoware packages into the ROS buildfarm about autoware

[mitsudome-r]

Thanks for creating the issue.
Although this would help a lot of ROS users, I would like to think carefully about the timing and the target package.

I propose to do this after we do a clean up of messages (replacing autoware_auto_msgs with autoware_msgs). This is because change in interface could be quite a disruptive change and we would like to have more organized interface before making it ROS "official" release.

Also, I think we should only release into the ROS buildfarm for the packages in Core considering the fact that we defined Core as AWF maintained package and Universe to be community maintained. Universe packages can be registered to ROS buildfarm by the owner of the package at their decision. As Core is currently empty, we should start with porting Universe packages into Core first before doing this task.

Absolutely! This issue is just meant to start the discussion and find out what steps we'd need if we ever want to release Autoware into the ROS buildfarm, but I don't think we're ready now to do it.

Sounds good. I found autowarefoundation/autoware_msgs#2 and I can work on it, if nobody else is working.

A priori I don't see the problem with releasing Autoware.Universe as well, but I understand that Autoware.Core is meant to be of higher quality, so it might make sense releasing it first.

However, the way package releases work with the ROS buildfarm is that bloom releases all the packages in a given repository (that's why it's required that all packages have the same version in their package.xml). So if we want to let community maintainers to release their packages on their own, they'll have to keep the packages in separate repositories and not all in Autoware.Universe. If anyone runs bloom on the Autoware.Universe repository, they'll release all the packages there.
