> Both fetchOffsetRequest and commitOffsetRequest handlers don't have
> sufficient logic to handle timeout exception.
>
> CommitOffsetRequest handler also doesn't handle various of server error such
> as coordinator not found. We need to handle:
> If Exception is non null:
> - handle RetriableError that respects requestTimeoutMs
> - handle NonRetriableError
>
> If the response contains error, ensure to:
> - mark coordinator unknown if needed
> - retry if needed
> - fail the request
