Backwards incompatability

This is a major rewrite of the Stream Replicator capability that now supports Choria Streams and NATS JetStream. As such this is not compatible with the old version, cannot just be upgraded to and configuration needs to be redone.

At present there is no Puppet module.

Enhancements

• Support Choria Streams and NATS JetStream
• Copy multiple streams in a single process
• Order preserving by default
• New dashboards
• Improved documentation in the Wiki
