NATS JetStream

Self-hosted Outpost can now use NATS JetStream for its internal delivery and log queues, alongside RabbitMQ, AWS SQS, GCP Pub/Sub and Azure Service Bus. Set NATS_SERVER_URL to enable it.

Stream, subject and dead-letter subject names can be overridden with the NATS_* variables. NATS servers limit messages to 1 MiB by default, so raise max_payload if you deliver larger events. See bring your own message queues.

Thanks to @rohanshirsath-droadmap for contributing NATS JetStream support. It's available now in v1.6.0.
