      Description

      A common problem with the new consumer is to have message processing take longer than the session timeout, causing an unexpected rebalance. Unfortunately, when this happens, the error messages are often cryptic (e.g. something about illegal generation) and contain no clear advice on what to do (e.g. increase session timeout). We should do a pass on error messages to ensure that users receive clear guidance on the problem and possible solutions.
