1. The RTPS IDs are now automatically assigned to the topics
2. Only the topics that get defined to be sent or received in the urtps_bridge_topics.yaml (renamed, since now it doesn't contain IDs) receive the IDs
3. Any addition or removal on the urtps_bridge_topics.yaml file might update the topic IDs - this will require that the agent and the client ID list has to be in sync. This will further require a robustification of the way we check the IDs and the message definitions when starting the bridge.
