This PR is intended as the foundation for a more efficient snapshot diff ([HDDS-9154](https://issues.apache.org/jira/browse/HDDS-9154)). This PR adds a `SnapshotDiffValueParser` with methods to deserialize required fields only from KeyInfo and DirectoryInfo for snapshot diff report generation. The list of fields that are deserialized: **From KeyInfo** - Required for all `fileTable`/`keyTable` entries under consideration : `keyName`, `objectID`, `parentID` - `updateID` is deserialized optionally only for full snapshot diffs. - For diff candidates that pass `updateID`/`sequenceNumber` gating fields required to build a compare signature(used to compare entries from the snapshots participating in the diff): - Fields indicating content change: `dataSize`, `fileChecksum`, latest block location - Fields indicating meaningful metadata change: `metadata`, `acls`, `tags` **From DirectoryInfo** - Required for all `fileTable`/`keyTable` entries under consideration : `name`, `objectID`, `parentID` - `updateID` is deserialized optionally only for full snapshot diffs. - For diff candidates that pass `updateID`/`sequenceNumber` gating fields required to build a compare signature: - Fields indicating meaningful metadata change: `metadata`, `acls`, ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-15387 ## How was this patch tested?
