Review Comment:
   @namrathamyske Each SnapshotProducer can implement their own validation 
logic 
https://github.com/apache/iceberg/blob/master/core/src/main/java/org/apache/iceberg/SnapshotProducer.java#L156
   
   This gets called when trying to apply the operation as part of validating 
conflicts. For example rewriting data files needs to validate that there are no 
new row level deletes for data files which were replaced: 
https://github.com/apache/iceberg/blob/master/core/src/main/java/org/apache/iceberg/BaseRewriteFiles.java#L108
   
   We should define the behavior of validation in the context of branching.
