Kolla environment currently uses haproxy
to fullfill HA in mariadb. This patch
is switching haproxy to proxysql if enabled.
This patch is also replacing mariadb's user
'haproxy' with user 'monitor'. This replacement
has two reasons:
- Use better name to "monitor" galera claster
as there are two services using this user
(HAProxy, ProxySQL)
- Set password for monitor user as it's
always better to use password then not use.
Previous haproxy user didn't use password
as it was historically not possible with
haproxy and mariadb-clustercheck wasn't
implemented.

Kolla Ansible
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.
Get started by reading the Developer Quickstart.
