Options gains Cluster{Name, Port, Routes, User, Password}, MaxStore,
MaxMemory and Generation. The server runs as <name>.<generation>, the
generation a random id persisted in StoreDir at first boot, so a raft
identity never outlives the log it was written with. Once current, a
node removes the offline older generations of its name from the meta
group. Ready wraps Healthz and requires JetStream current; Shutdown is
lame duck; routes without credentials are refused.
The "no raft" line in the package doc is rewritten: JetStream R3 is
NATS raft.
