Replace sim launch approach #31
Description
Summary
Currently the simulation is being launched via a ROS 2 launch file that ultimately calls the python.sh script in the Isaac install folder and passes it out custom python launch script. This means that we need to compile and source a ROS 2 workspace when it isn't necessary.
We should modify this in order to launch the simulation by directly calling the python.sh script and passing it our script found in tools/isaac_launch_script.py. This can further be enhanced by making the docker entrypoint launch the simulation directly, making the experience for the user less involved.
We can also provide another entrypoint for developer who would like to develop inside the container instead of just running the simulation
