[feature] Provide changelog-producer.row-deduplicate to deduplicate same change

[JingsongLi]

In lookup and full-compaction changelog-producer, same record will produce -U and +U, but they are the same.
We can provide a option to avoid producing changelog for the same record.

I want to do it. Could you assign it to me?

@JingsongLi Can this option default be true? Are there use case will rely on the same value -U and +U value ?
