    Description

      A replica vbucket can be serving DCP clients (currently only view engine). When a replica vb rolls back due to any reason (usually dictated by changes on the corresponding active vb of that replica), we should ideally close the any on-going DCP streams and indicate the client to rollback in the subsequent request.

      Also, we must handle the case of a rollback occurence when a DCP client stream is being created.
