    Description

      Original Downstream Change Summary

      shardCollection and refineCollectionShardKey parameters have been created but we don't want to document them publicly. Those parameters will appear in op: c oplog entries.

      Epic Summary

      Summary

      Add a new field to the shardCollection command to relax uniqueness requirements during validation and to prevent it from creating new indexes.

      Motivation

      This will be needed by the [cluster to cluster replication|REP-33] so it can have full control of what kind of indexes can be created in the destination cluster. For example, no unique indexes other than the _id index.
