> Current scheduler based timeout mechanism is per batch, which isn't efficient. HashedWheelTimer is much better for timeouts. So change the PCBC to use HashedWheelTimer for timeouts.
> Besides that HashedWheelTimer change, it also provides multiple channel per bookie support for latency consideration.
