调整了 pod 的属性元组，新增了 node 的属性元组

            // node attribute tuple (cluster, node, role, host_ip) ==> 1
            // role priority: edge > control-plane > worker > other > ""
            //
            record: 'node_role_ip:kube_node_info:',

节点 role 将通过 node_role_ip:kube_node_info 进行关联，不在关联 pod 属性元组
