> - Add a new message, {{RateUpdate(newRate: Long)}} that ReceiverSupervisor handles in its endpoint 
> - Add a new method to ReceiverTracker
> {{def sendRateUpdate(streamId: Int, newRate: Long): Unit}}
> this method sends an asynchronous RateUpdate message to the receiver supervisor corresponding to streamId 
> - update the rate in the corresponding block generator.
