Overriding configuration template

If you can't customize via variables because an option isn't exposed, you can override the template used to generate the haproxy configuration file.

haproxy_conf_template: "etc/haproxy/haproxy.cfg.j2"

You can either copy and modify the provided template, or extend it with Jinja2 template inheritance and override the specific template block you need to change.
