Is your feature request related to a problem or challenge?

To detect conflicts, we need to have validate and related logic to scan manifests and validate against history.

Describe the solution you'd like

Add related logic to SnapshotProduceOperation so different actions like RowDelta, OverwriteFiles, and RewriteFiles can use and override (if needed)

predicate/residual evaluator and manifest filter are also important (to reduce conflict rate) but they could be completed separately, wdyt? @Xuanwo @liurenjie1024 @jonathanc-n

Yes those can be completed separately, I will try to get residual evaluator done (a bit difficult since the schema + filters in rust are a bit different)
