Thinking about this a bit more. It seems that a better approach is to move the 
decoding into MessageAndMetadata. We define two methods key() and message() 
that do the decoding and throw a RuntimeException back to the caller if 
decoding fails. This way, the client can still get the metadata (offset, 
partitionId, etc) associated with a message even when decoding fails.
