    Description

      Each document on config.chunks has its own ChunkVersion. Since we extended the definition of ChunkVersion to include a timestamp, when we are upgrading/downgrading we have to properly handle it.

      On upgrade we should add to all docs on config.chunks the same timestamp that we are adding to config.collections. On Downgrade we have to get rid of it, as we do in config.collections.
