Comment: Fix incorrect default identified by Jeff Widman


We've reduced the default session timeout, but actually increased the amount of time given to consumers for message processing to 60 seconds5 minutes. We've also set a fairly conservative max.poll.records to give users a more reasonable default batch size to avoid the need for many users to tune it in the first place (the current default is Integer.MAX_VALUE).
