    Description

      Update https://docs.mongodb.com/manual/tutorial/build-indexes-on-replica-sets/: 

      If an index is built by taking a node out of the replica set, building an index on it, then putting it back into the replica set (as is our documented process for building indexes in a replica set), then there won't be an oplog entry generated for the index build. Without an oplog entry for the index build, BRS has no way to discover that that index was built.

      We should document this behavior, and maybe consider building a way for users to inform BRS of the new index.
