Hi - thanks for the PR
Sorry for the delay in reviewing it. Overall, I think this makes sense.
Few minor comments. Also, can you reset the changes to REFERENCE.md? We can rebuild it when cutting the next release.
Question: your commit seems to be from @openiobot - can you amend the author to be your own GH username?

When overriding local node name (using NODENAME environment variable), clustering does not work as tinit_node is tested again hostname or fqdn. By adding the optional local_node to specify which node is the current node we can fix this issue. Use case: a server with a public and a private interface, rabbitmq cluster nodes communicates through the private interface while hostname and fqdn resolves to the public interface (and that can't be changed because of other dependencies on the server). The only solution is to use dedictated name for the private interface.
