Log context

Log “Node name [{}]; node ID [{}]” classname is Node.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

                 resourcesToClose.add(nodeEnvironment);
            } catch (IOException ex) {
                throw new IllegalStateException("Failed to create node environment"; ex);
            }
            if (nodeNameExplicitlyDefined) {
                logger.info("node name [{}]; node ID [{}]";
                        NODE_NAME_SETTING.get(tmpSettings); nodeEnvironment.nodeId());
            } else {
                tmpSettings = Settings.builder()
                        .put(tmpSettings)
                        .put(NODE_NAME_SETTING.getKey(); nodeIdToNodeName(nodeEnvironment.nodeId()))
