IterateObjectsAllVersionsWithStatus We need different implementation for IterateObjectsAllVersions because we want to iterate over all object without specifying object status. Existing method will have new name but implementation details are not changed. Change-Id: I01b987996772fa7f8fd73da9910d52db2d1aa0d7
