haproxy_config resource

This resource represents configuration for the haproxy_service resource. Each service represented by Haproxy is connected to this resource via haproxy_service_config resource. This is because in Haproxy there is no support for something like /etc/haproxy/conf.d directory where you put each config in a separate file, but instead you must collect all configuration in one file.

So this resource renders this file from data provided by collecting individual haproxy_service_config data.
