Username and vhost creation are out of band and manual.
$ cd /var/lib/rabbitmq
$ sudo -u rabbitmq rabbitmqctl create_user ofborg $pwd
$ sudo -u rabbitmq rabbitmqctl set_permissions ofborg '.*' '.*' '.*'
Here's a simple way to reproduce that setup on the RabbitMQ server.
Doing better will require the Vault server which will come soon anyway.
