!per #15377 Mandate atomic writes for persistAll, and support rejections

Browse source 
* changing Plugin API for asyncWriteMessages and writeMessages
* passing explicit AtomicWrite that represents the events of
  persistAll, or a single event from persist
* journal may reject events before storing them, and that
  will result in onPersistRejected (logging) and continue in the
  persistent actor
* clarified the semantics with regards to batches and atomic writes,
  and failures and rejections in the api docs of asyncWriteMessages
  and writeMessages
* adjust the Java plugin API, asyncReplayMessages, doLoadAsync
