Investigate changes in SERVER-56296: Uniform `fromNss == toNss` rename behavior between rs and sharded cluster

XMLWordPrintableJSON

      Description

      Downstream Change Summary

      Just for the record, don't know if the corner case was taken into account previously.

      If a user tries to rename a collection to itself, starting from now an IllegalOperation is thrown. Before, a misleading NamespaceNotFound exception was thrown.

      Description of Linked Ticket

      If the collection exists, the collection version must be returned in a best-effort fashion, without acquiring any lock.

      If the collection exists but dropTarget=true, an `IllegalOptions` error must be returned.

      If the collection doesn't exist, a `NamespaceNotFound` error is already thrown both in case of RS or sharded cluster.
