title: cloudControl - PHP: (temporarily) disable composer
body: <p>I am happily developing a PHP app using <a href="http://getcomposer.org/" rel="nofollow">Composer</a> on cloudControl. 
  It's great how it is integrated into the deployment procedure.
  However, there's no need for Composer to update on <em>every</em> deploy.</p>
  
  <p>Is it possible to (temporarily) disable Composer, per deployment?</p>
  
  <p>Thanks in advance.</p>
