   @satishkotha Couple of high level questions:
   * Would preserving commit time be sufficient to support incremental read? 
Won't we need incremental timeline support (#2388 ) as well? 
   * I see that a new `SparkAllowUpdateStrategy` has been added. How are we 
handling update conflicts?

> As part of clustering, metadata such as hoodie_commit_time changes for 
> records that are clustered. This is specific to 
> SparkBulkInsertBasedRunClusteringStrategy implementation. Figure out a way to 
> carry commit_time from original record to support incremental queries.
> Also, incremental queries dont work with 'replacecommit' used by clustering 
> HUDI-1264. Change incremental query to work for replacecommits created by 
> Clustering.
