## What changes were proposed in this pull request?
This PR introduces refactors the pending deletion metadata handling logic
and comprehensive integration testing for the DataNode data distribution
feature upgrade scenario.
The changes include:
1. **Code Refactoring**: Refactored to improve the pending deletion metadata
handling: `KeyValueContainerUtil.java`
- Extracted `populatePendingDeletionMetadata()` method for better
separation of concerns
- Added separate handler methods for different upgrade states
- Enhanced the conditional logic to properly handle DATA_DISTRIBUTION
feature finalization
- Improved code readability and maintainability
2. **Integration Test Addition**: Created with comprehensive test coverage
for the DN data distribution upgrade scenario, specifically validating:
`TestDNDataDistributionFinalization.java`
- Pre-finalization behavior (handlePreDataDistributionFeature path)
- Post-finalization behavior (handlePostDataDistributionFeature path)
- Missing metadata recalculation scenario (getAggregatePendingDelete
path)
