[here|https://docs.google.com/document/d/1ls_g5fFmfbbSTIfQQpUxH56d0f3OksF567zwA00zK9E/edit?usp=sharing]
- 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.
