fix: remove the Id field from response of GET, POST /bridges

The response body of POST, GET /bridges should be the same as
 the request body of the POST /bridges:

```
{"type": "mqtt",
 "name": "my_mqtt_bridge"
}
```

We force the user to provide an Id of format `{type}:{name}` when GET,
DELETE, PUT a bridge:

`GET /bridges/{type}:{name}`
