add LoadSnapshotFailed in snapshot protocol, #21842

Browse source 
* treat snapshot load failure in same way as other recovery failures
* if load of snapshot fails the persistent actor will be stopped, since
  we can't assume that a consistent state would be recovered just by
  replaying all events, since events may have been  deleted
* additional recovery docs
* improve log message
