cluster.shutdown
* must also be done when the listener actor stops before the
MemberRemoved event has been received
* add test for this
* clarify docs with example that shuts down actor system and
exit jvm

* remove final identifier in serializers
i* revert/deprecate ProtobufSerializer.ARRAY_OF_BYTE_ARRAY
* adding back compatible empty constructor in serializers
* make FSM.State compatible
* add back ActorPath.ElementRegex
* revert SocketOption changes and add SocketOptionV2

* problem filter for ActorDSL
* event bus
* exclude hasSubscriptions
* exclude some problems in testkit
* boundAddress and addressFromSocketAddress
* Pool nrOfInstances
* PromiseActorRef
* check with 2.3.9
* migration guide note
* explicit exclude of final class problems
* in the end TestKitBase eagerly initialize the ActorSystem and
to avoid the need for using lazy val tricks I changed the trait
to abstract class with config constructor parameter
* and don't show AkkaSpec in doc code

* 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
This is the first step towards more type-safety in Actor interactions,
comprising:
* generic ActorRef[T] that only accepts T messages
* generic ActorSystem[T] extends ActorRef[T] (sending to the guardian,
whose Props[T] are provided for ActorSystem construction)
* removed the Actor trait: everything in there has been made into
messages and signals
* new Behavior[T] abstraction that consumes messages (of type T) or
Signals (lifecycle hooks, Terminated, ReceiveTimeout, Failed),
producing the next Behavior[T] as the result each time
* the ask pattern is provided and yields properly typed Futures
* variants of ActorContext are provided for synchronous testing of
Behaviors
All of this is implemented without touching code outside akka-typed
(apart from making guardianProps configurable), creating wrapper objects
around ActorRef, ActorContext, ActorSystem, Props and providing an Actor
implementation that just runs a Behavior.
