title: How to get the Elasticserch version using the Elasticsearch ruby gem?
body: <p>The Elasticsearch ruby gem (defined <a href="https://github.com/elastic/elasticsearch-ruby" rel="nofollow noreferrer">here</a>) doesn't seem to expose a method for getting the Elasticsearch version on the cluster to which you are connecting.  (Though I might just be missing it.)  </p>
  
  <p>Is there a way to do so from the gem (other than curling port 9200, as described <a href="https://stackoverflow.com/questions/34822244/">here</a> )?</p>
