trait Extension extends AnyRef
Marker trait/interface for extensions. An extension can be registered in the ActorSystem and is guaranteed to only
have one instance per ActorSystem instance per ExtensionId. The extension internals must be thread safe.
For mutable state it should be preferred to use an Actor rather than extensions as first choice.
