Docker distribution

I feel the rtatmt4ros itself, we don't need to make it docker.
Because, sharing pkg level in docker is not common, and most of all user want to you it as pkg if they are ROS users.

I think we can keep the repo. as ROS pkg, but we can call rtamt docker instead of install it in host python.

I understood Bardh's intention.
For very beginner of ROS perhaps who fail to install ROS can not run it. We need to consider all in one Docker version of rtamt4ros too. I think we need to implement two version.

• all Docker ver: very biggner
• rtamt runs on Docker, but still rtamt4ros side works as ROS pkg :somehow middle level.
