What changes were proposed in this pull request?
This PR handles failed container import cleanup on the DataNode.
KeyValueContainer.cleanupFailedImport()now deletes the chunks/ directory before deleting the metadata/ directory. If cleanup is interrupted or partially fails between child-directory deletions, the remaining on-disk state now preferentially preserves metadata instead of leaving a harder-to-diagnose chunks/-only residual directory.
A focused test was added to inject an import cleanup failure at metadata deletion and verify that chunks/ has already been removed while metadata/ remains.
