Added another commit for long-running time-based lease for manifest and config blobs. This should be rewritten after containerd/containerd#3295 containerd/containerd#3307 with completely removing root labels, that should fix the need for buildkit taking ownership of the namespace and properly clean up canceled pulls. |

This fixes a race where gc cleans up a ref that holds the same blob that is pulled by another ref. Now blobs are kept by a lease during pull, avoiding containerd for cleaning them up. And inserting a blob mapping recreates the root label.
fixes #992 (traces in #991)
