Check_MK Werk 6060: Clusters: Add missing custom variable containing the node names

ID: 6060 Title: Clusters: Add missing custom variable containing the node names Component: Core & setup Level: 1 Class: Bug fix Version: 1.6.0i1 In addition to the existing custom attributes _NODEIPS, _NODEIPS_4 and _NODEIPS_6 this change adds a new variable _NODENAMES. All the entries in this variables are now sorted by the node name. This means that e.g. the 2nd entry in all of the above variables belongs to the same node.
