Checkmk Werk 12789: kubernetes: nodes: fix labelling

ID: 12789 Title: kubernetes: nodes: fix labelling Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0i1 Before this werk, the host fetching the data via the special agent was labeled <tt>cmk/kubernetes_object:master</tt>. After this werk kubernetes nodes are labeled with either <tt>cmk/kubernetes_object:worker_node</tt>, or <tt>cmk/kubernetes_object:control-plane_node</tt>. The host fetching the data via the special agent is labeled <tt>cmk/kubernetes_object:cluster</tt>. If you have rules that use the <tt>cmk/kubernetes_object:master</tt> label you have to update your rules to use the new labels.
