title: Remove service on docker-compose through overriding
body: <p>I want to remove a container defined in docker-compose.yml file when we run in composition/override with another file docker-compose.prod.yml, by example:</p>
  
  <pre><code># docker-compose.yml
  version: 2
  services: 
  
    www:
      image: php56
  
    db_for_development:
      image: mariadb
  </code></pre>
  
  <p>override with:</p>
  
  <pre><code># docker-compose.prod.yml
  version: 2
  services: 
  
    www:
      image: php70
  
    db_for_development:
      [control: override-and-remove] # hypothesis
  </code></pre>
  
  <p>Then, when running:</p>
  
  <pre><code>docker-compose -f docker-compose.yml -f docker-compose.prod.yml up -d
  docker-compose -f docker-compose.yml -f docker-compose.prod.yml ps
  </code></pre>
  
  <p>Actually, i have <code>www</code> and <code>db_for_development</code> together.</p>
  
  <p>I want only <code>www</code> container, not others.</p>
