haproxy configured and running before mysql, keystone, etc

Moving haproxy config *before* mysql, keystone, etc.  Note that dependencies have been removed around quickstack::load_balancer::* classes (e.g. class {"::quickstack::load_balancer::cinder": ) within individual service manifests so their contribution to haproxy.cfg actually gets "executed" in ::quickstack::pacemaker::load_balancer without causing dependency cycle issues.
