Certain services such as Murano and trove require access to a rabbitmq instance from tenant networks. [0] Exposing the internal rabbitmq to end users is a security hole, hence there are two options, 1) use vhosts in the existing rabbitmq, or two a separate rabbitmq instances. Given the importance of rabbitmq to the OpenStack deployment, we have decided to go with a separate instance. Refer to [1] for more detail on the various options. This change makes the rabbitmq role generic so that it can be reused, in this case to start 'outward_rabbitmq'. It needs to be exposed via haproxy both for network isolation and also because this is what Murano configuration requires. Follow on patches will be added to add a vhost in this outward instance for Murano and other services which require access.

Kolla-Ansible Overview
The Kolla-Ansible is a deliverable project separated from Kolla project.
Kolla-Ansible deploys OpenStack services and infrastructure components in Docker containers.
Kolla's mission statement is:
To provide production-ready containers and deployment tools for operating
OpenStack clouds.Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.
Getting Started
Learn about Kolla-Ansible by reading the documentation online docs.openstack.org.
Get started by reading the Developer Quickstart.
