Review comment:
@Victsm that's a good point but we can still replace the usage of
`StaleBlockPushException` which is created with a message that uses
`String.format` with `BlockPushNonFatalFailure`. We can still catch
`BlockPushNonFatalFailure` and based on the `ErrorCode` enum differentiate
between stale and too late.
Also, for stale block pushes that are for prior application attempts, isn't
closing the channel better? For clients that are pushing blocks from prior
application attempt, we just want them to stop pushing all together correct?
