> The transaction timeout is set to 1 minute by default on Producer today, 
> while the commit interval on the other hand could be set to a very large 
> value, which makes the stream always hit transaction timeout and drop into 
> rebalance. We should increase the transaction timeout correspondingly when 
> commit interval is large.
> On the other hand, broker could have a limit on the max transaction timeout 
> to be set. If we scale up client transaction timeout over the limit, stream 
> will fail due to  INVALID_TRANSACTION_TIMEOUT. To alleviate this problem, 
> user could define their own customized transaction timeout to avoid hitting 
> the limit, so we should still respect what user configures in the override.
> The new rule for configuring transaction timeout should look like:
> 1. If transaction timeout is set in streams config, use it
> 2. if not, transaction_timeout = max(default_transaction_timeout, 10 * 
> commit_interval) 
> Additionally if INVALID_TRANSACTION_TIMEOUT was thrown on Streams when 
> calling initTransaction(), we should wrap the exception to inform user that 
> their setting for commit interval could potentially be too high and should 
> adjust.
