Back in time in MongoDB v2.6 and v3.0, the option sharding.archiveMovedChunks was enabled by default and was aimed at making the source shards archive all migrated documents in a directory named after the collection namespace under the moveChunk directory in the storage.dbPath.

Since this feature has long been disabled, purpose of this ticket is to get rid of all the code unused in all currently supported and future versions:

• Delete those parameters and their usages
• Get rid of the RemoveSaver from the migration destination manager and delete stage params
