 Description   

This is motivated by:

The MigrationSourceManager needs to be able to access the chunk it is migrating's ChunkVersion. That version will then be sent with the CommitChunkMigration command. The CommitChunkMigration command will then do a query to check that the chunks it receives are valid, i.e. exist in the config.chunks collection.

This won't actually work as intended because the CollectionMetadata only stores chunk ranges, not ChunkVersions. Closing.
