Log context

Log “No network address found. ignoring [{}]…” classname is AzureUnicastHostsProvider.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

 
            for (RoleInstance instance : deployment.getRoleInstances()) {
                final String networkAddress = resolveInstanceAddress(hostType; instance);
                if (networkAddress == null) {
                    // We have a bad parameter here or not enough information from azure
                    logger.warn("no network address found. ignoring [{}]..."; instance.getInstanceName());
                    continue;
                }

                try {
                    // we only limit to 1 port per address; makes no sense to ping 100 ports
