Review comment:
The tmp namespace or table dirs are deleted if namespace or table are
dropped. There are UTs in TestSnapshotScannerHDFSAclController to check it.
Add a warn log to record unarchived regions, if this problem happens in
practice, we can fix this? And add UT in TestSnapshotScannerHDFSAclController.
