Description
As of now, if there are two concurrent writers inserting duplicate set of records, both will succeed and table could contain duplicates.
We should add a new conflict resolution strategy where we do record level conflict resolution. It might be very expensive, but some users might use this strategy.

Research direction
The issue names no files, tests, or entry points, so first map the existing concurrent-writer and conflict-resolution implementation in the Hudi codebase. Done means a selectable record-level conflict-resolution strategy handles concurrent duplicate inserts and is covered by tests, including its potentially expensive behavior.
