This change renames the root transformer to indicate that it operates on host paths and adds a container root transformer for explicitly transforming container roots. The transform.NewRootTransformer constructor still exists, but has been marked as deprecated. Signed-off-by: Evan Lezar <elezar@nvidia.com>
