Access camera-api from host machine & challenge `network_mode`

[fe51]

Pitch

TODO after #312

From the host machine (like when doing local dev, and running docker compose on personnal laptop), it is not possible to reach the swagger to read the api docs.

What is done currently

• network_mode:host is used, but not sure if it is useful here (need to work on raspberry pi and any server linux, or mac) -> To be challenged

What should be done

• Must be investigated but adding port forwarding in docker compose of the camera_api service might solved the issue

ports:
    - "8081":"8081"

At last, it is needed that the camera_api services is accessible from outside on the port 8081

Happy to discuss it !
