[Arena] Add a room_id to the simulation profile and implement the new interface #62
Description
Since we do not currently store the complete history of agents’ chats, it would be beneficial to add a room for agents by including room_id in the config file. There are already some implementations of this in certain workers. This improvement could provide significant advantages. I believe the concept of rooms is similar to stages. We can discuss this further to find a solution or consider merging them.
