Implement "rooms"

[susliko]

We're going to have a "room" entity in our app. This is a place with unique identifier, which can be joined to use video-chat capabilities.
We need REST operations to create/join rooms:
POST /room/create

• receives: nothing (?)
• responds: unique room identifier

POST /room/join

• receives: nothing (?)
• responds: (?)

Should we think about unused rooms cleanup? What overhead does an existing room have?

I've created Room entity like this:

class Room(BaseModel):
    id: str = random_short_id()
    users: List[str] = []  # todo: make set()?
    creator: str
    worker_id: str

Do we want user names to be unique in one room? Now it is not unique, maybe it could be problem for workers to identify user when establishing connection

Also we have Worker entity:

class Worker(BaseModel):
    id: str
    url: str
    capacity: int = 1
    filled: int = 0

Worker is responsible for interacting with users. One Room belongs to one Worker, Worker could have multiply Rooms, ideally up to Worker.capacity

When user creates Room, it is automatically scheduled to the less busy Worker

When user joins Room, response is Room object contains worker_id. To get url to connect to, this request should be done to fetch Worker: http://zumba.salamantos.me/docs#/default/get_worker_by_id_worker_id__worker_id___get
