The MariaDB role HAProxy config section exposes MariaDB on the mariadb_port which may not always be the same as database_port. The HAProxy role checks that the database_port is free, and not the mariadb_port. This could mean that the check passes, but the actual port which HAProxy will attempt to use is taken. This change configures HAProxy to talk to the MariaDB instances on the mariadb_port, and maps them to the database_port which is used by most services as part of the DB connection string. There is a small risk that it may break someones override config. Change-Id: I9507ee709cb21eb743112107770ed3170c61ef74

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 Kolla-Ansible.
