> 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
