* we need to read the higestSeqNr anyway and it is better
to do it first and limit the asyncReadHighestSequenceNr
to that (instead of Long.MaxValue)
* return the highestSeqNr in the ReplayMessagesSuccess
* this also removes one become state in PersistentActor recovery
logic
+ LambdaDoc samples now in the docs project
= simplified internal state by removing recoveryPending
= recovery is now triggered in around* method, so user is free to use
preStart freely - recovery works even if one forgets to call super on
preStart
* also improved fault handling in various places (bugs found)
* and manually triggered Update must be distinguished from scheduled
auto updates, otherwise manual Update will schedule extra auto updates
* remove channels
* remove View
* remove Processor
* collapse the complicated internal state management
that was spread out between Processor, Eventsourced and Recovery
* remove Recovery trait, this caused some duplication between Eventsourced
and PersistentView, but but the enhanced PersistentView will not be based
on recovery infrastructure, and therefore PersistentView code will be replaced anyway
* remove PersistentBatch
* remove LoopMessage
* remove deleteMessages of individual messages
* remove Persistent, PersistentRepr and PersistentImpl are kept
* remove processorId
* update doc sample code
* note in migration guide about persistenceId
* rename Resequencable to PersistentEnvelope
A PersistentView works the same way as View did previously, except:
* it requires an `peristenceId` (no default is provided)
* messages given to `receive` are NOT wrapped in Persistent()
akka-streams not touched, will update them afterwards on different branch
Also solves #15436 by making persistentId in PersistentView abstract.
