 Description   

Currently in secondary oplog application, a prepareTransaction oplog entry  is applied in its own batch and fillWriterVectors() simply adds it to the writeVector that is responsible for the `admin.$cmd` namespace. This ticket will instead find all the CRUD entries in the prepared transaction when encountering a prepareTransaction oplog entry in fillWriterVectors(), split them by nss/_id and dispatch them to the various writerVectors.
