ClusterExtension

Defined in: src/cluster/ClusterExtension.ts:21
Holds the Cluster this ActorSystem joined, so that anything
holding the system can reach it — system.cluster,
context.cluster, this.cluster — instead of having it threaded in
by hand.
Cluster.join is the only writer. That keeps the invariant simple:
the slot is filled exactly when a cluster exists, and nothing else
has to remember to register.
It stays Option rather than being created on demand because a
cluster is not free — it binds a transport and starts gossip,
heartbeat and failure-detection timers. A local-only system must
never grow one just because someone asked.
