[Feature]: Visualization of cars in the 3D Map for the intermediate layer

[SirMDA]

Feature Description

For a PoC of the intermediate layer we not only need the data and data structure but also a visualization.
This feature should include following:

• Research on how visualization can be done
• Research how to get the information of the car coordinates through the object detection by the camera (partially already existing)
• Check which models are implemented and what they are capable of
• Best case implement a first throw on how the objects could be visualized in Rviz

Definition of Done

• Research on how visualization can be done
• Research how to get the information of the car coordinates through the object detection by the camera (partially already existing)
• Check which models are implemented and what they are capable of
• Best case implement a first throw on how the objects could be visualized in Rviz

Effort Estimate

3 - 4 d

Testability

As this will only be a PoC this will not be tested yet.

Dependencies

I created a first prototype of the map visualization.
Inspired by the class diagram provided in the brainstorm issue #494.

In the screenshots you can see two Entities inside the map. Red entities are collidables, green ones not.
In the second screenshot the collidable filter is activated. Therefor only the red one shows.

As a RVIZ Panel is needed for this catkin_make must be executed.
In #420 I implemented the functionality to execute catkin_make in the containers.
The current workflow for testing is:

1. Stop leaderboard
2. Execute catkin_make in dev container
3. Start leaderboard
4. Execute catkin_make in agent container
5. Execute catkin_make in agent-dev container
6. Add the panel in rviz

(The visualization node has to be started seperately as well)

As you can see before this can be deployed this infrastructure issue has to be dealt with.
