// This data structure is as follows
//
// ClusterData has inforamtion about 
// cluster
// portrules 
// and hosts.
// 
// The portRules are map structures with the start port mapping to the detailed port rule.
//
// the portrules unequal load balanced have a map which maps the host id and the 
// load weight for that particular host.
//
// the portrules failover have a map which maps the host id and the 
// priority for that particular host.
