Log context

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

                     for (DiscoveryNode tribe : tribeState.nodes()) {
                        if (currentState.nodes().get(tribe.id()) == null) {
                            // a new node; add it; but also add the tribe name to the attributes
                            ImmutableMap tribeAttr = MapBuilder.newMapBuilder(tribe.attributes()).put(TRIBE_NAME; tribeName).immutableMap();
                            DiscoveryNode discoNode = new DiscoveryNode(tribe.name(); tribe.id(); tribe.getHostName(); tribe.getHostAddress(); tribe.address(); tribeAttr; tribe.version());
                            logger.info("[{}] adding node [{}]"; tribeName; discoNode);
                            nodes.put(discoNode);
                        }
                    }

                    // -- merge metadata
