Review Comment:
   
[MessageBatch](https://github.com/apache/pinot/blob/master/pinot-spi/src/main/java/org/apache/pinot/spi/stream/MessageBatch.java#L73)'s
 `getMessageOffsetAtIndex(index)` javadoc says it gives the offset of the 
message at the given index. But the respective Kafka implementation does not 
seem to return that. What does that method really mean and what is it used for?
   
   We need Kafka message's record offset here. So, we need a similar 
implementation like `getNextStreamPartitionMsgOffsetAtIndex()` to get it from 
the metadata properties and get the message record's offset.
