title: Elastic4s dependency to org.elasticsearch, can I get rid of it?
body: <p>I just realized that elastic4s has a dependency to org.elasticsearch, and that dependency is downloading 20 Mb of library. </p>
  
  <p>For what I have seen in the github repo for elastic4s there are 66 references to the package org.elasticsearch in the code. Nevertheless as far as elastic4s is a client, I was wondering if there is a way to get rid of it of this dependency, or at least make it less heavy. </p>
  
  <p>Any thoughts on this are welcome?</p>
  
  <p>Thanks in advance. </p>
