title: Feign + Ribbon request interception AFTER target host is choosen
body: <p>What I'm currently doing (which is very simple and convenient way):</p>
  
  <pre><code>Feign.builder()
  .client(RibbonClient.create())
  ...
  .requestInterceptor(new MyInterceptor())
  </code></pre>
  
  <p>But interception occur before ribbon actually resolve target host. 
  Problem is, that one header that I want to add, have to be created based on the name of the target host.</p>
  
  <p>Is there anyway I can manipulate headers after host is resolved?</p>
