Incomplete APIs

[adar2378]

Hi I am checking api methods and models on https://github.com/djangoflow/flutter-djangoflow/tree/main/packages/djangoflow_openapi

I see after the latest refactor few things went missing.

Critical ones:

• [x] Room id should be String instead of int . Currently in every API we use int type but for some reason GET /api/v1/chat/rooms/{id}/ uses String. But all should be String type.
• [x] No API get the users that are in a room(need it to display who sent which message, and which one user is me, previously there used to be RoomUser model that used to give information like id, name, avatar etc of the user)
• [x] GET /api/v1/chat/rooms/{room_id}/messages/ does not support limit , offset parameter passing for pagination

Less critical ones:

• [ ] #53
• [ ] #54
• [ ] #55

No API get the users that are in a room

Add DEFAULTS to USER_SERIALIZER_CLASS.

by default it should be id, first_name, last_name. Make sure, we send full UserSerializer object in websocket response.
