Support RowDeltaAction

[ZENOTME]

Is your feature request related to a problem or challenge?

As #798、#1081, there are requirements for append delete data files (position delete, equality delete). This action is used to support the append of this kind of file.

Describe the solution you'd like

The path to support:

• add conflict detection
• add retry logic Support commit retrie #964
• complete RowDeltaAction

For metadata conflict detection, what is the exact design outline that you are looking to implement?

For the row level detection I can start the implementation the manifest filter manager and manifest merge manager to build towards the merging snapshot producer used in the RowDelta. This can probably be done after delete files are fully implemented

conflict detection implementation based on the validation phase. I would like to introduce the validation phase at SnapshotProduce apply(). After introducing it, we can have some specific implementation of kinds of validation.

For the row level detection I can start the implementation the manifest filter manager and manifest merge manager to build towards the merging snapshot producer used in the RowDelta. This can probably be done after delete files are fully implemented

Thanks @jonathanc-n!

• For manifest merge manager, I think it has been cover in feat: support merge append action #902.
• For manifest filter manager, maybe we need it. One interesting finding is that pyiceberg don't have the manifest filter manager. In this abstraction, it filter the delete entry directly. I haven't dive into the manifest filter manager, is needed in the future? cc @Fokko @kevinjqliu

I'll take a deeper look into the implementation tomorrow

@ZENOTME Sorry for the delay, i was a little busy with family. In the example you showed in the python implementation, the filtering for OverwriteFiles and DeleteFiles seems to be inherited from the snapshot producer. We could create the MergingSnapshotManager or something similar and have it be called when an action that produces a new snapshot. I think we do still need some things before this happens.

One thing I would like to implement before the filter manager are residual predicates mentioned by @Fokko here
