Review comment:
> For stale push from prior app attempt, it currently indeed throws an
IllegalArgumentException inside receiveBlockDataAsStream which would lead to
server closing channels.
I see. That's right. I missed that stale push here is used only in reference
to the executors which are for the same app attempts but older merged id.
But anyways, I still think we should replace `StaleBlockPushException` usage
with `BlockPushNonFatalFailure`.
