I have the same requirement. Several teams has and will have their services defined in the haproxy, what I do implement is a schema where configurations are included to produce a central file. This is working on Solaris 10/SPARC

Every configuration is defined by a file located in a folder named haproxy.d, names has /etc/init.d like syntax dda+

Script annexed.

Hopping this help.
