func BuildVirtualHost 

func BuildVirtualHost(svc *model.Service, port *model.Port, suffix []string, routes []*HTTPRoute) *VirtualHost

BuildVirtualHost constructs an entry for VirtualHost for a destination service. The unique name for a virtual host is a combination of the destination service and the port, e.g. "svc.ns.svc.cluster.local:http". Suffix provides the proxy context information - it is the shared sub-domain between co-located service instances (e.g. "namespace", "svc", "cluster", "local")
