- generate node names when transforming from simple to cluster config
- ClusterCreate(clusterconfig) should have a ready made config and not
generate variables
- ClusterCreate() only prep LB if not already present (to be removed)
- cluster struct: serverloadbalancer is now of type LoadBalancer (Node +
Config)
- use new nodefilter syntax with 'id:index:suffix' instead of
'id[index]' everywhere
- use suffix when creating the LB
