We want to use the time in Humble to migrate to Ignition for Nav2 moving forward.

• Migrate AWS warehouse world to Ignition
• Provide TB4 simulation launch file (tb4_simulation_launch.py) for Ignition analog to TB3 for Gazebo using whatever standard launch file provided by TB4 (I believe its a warehouse)
• Update simple commander examples to using Ignition with the AWS warehouse world migration
• Migrate system tests to using ignition with AWS warehouse world after Migrate to AWS warehouse simulation scenario #2797 is merged
• Consider updating TB4 simulation launch examples to using the AWS warehouse world that the system tests and simple commander API uses. Or migrate all a different warehouse. Doesn't have to all be the same, but consider it.
