[Feature]: NATS Cluster

[bearrito]

Problem

No

Solution

Implement a NATS cluster. I think conceptually it would be close to the Kafka implementation.

Equivalent to following the steps here - https://docs.nats.io/running-a-nats-service/nats_docker#creating-a-nats-cluster

Benefit

A user (me) could test inter-cluster features.

Alternatives

1. Just use a single node.
2. Run the cluster out of band.
