title: Jmxtrans Config for multiple queries to the same Writer
body: <p>While setting up metric reporting for Apache Kafka to ElasticSearch with jmxtrans, we have written a configuration file that queries about 50 metrics. </p>
  
  <p>The queries are as follows: </p>
  
  <pre><code>{ 
    "obj" : "kafka.server:type=BrokerTopicMetrics,name=TotalFetchRequestsPerSec", 
    "outputWriters" : [ { 
      "@class" : "com.googlecode.jmxtrans.model.output.elastic.ElasticWriter", 
      "connectionUrl": "http://elasticHost:9200" 
    }] 
  }
  </code></pre>
  
  <p>Since there are so many of them all writing to the same destination, is there a way in the config file to shorten this?</p>
  
  <p>Any help is highly appreciated.  </p>
