title: apt-get --simulate dist-upgrade without notice
body: <p>I want to do simulation of dist-upgrade without notice about simulation:</p>
  
  <blockquote>
    <p>NOTE: This is only a simulation!
          apt-get needs root privileges for real execution.
          Keep also in mind that locking is deactivated,
          so don't depend on the relevance to the real current situation!</p>
  </blockquote>
  
  <p>I found that there is some option that turned on by default: "APT::Get::Show-User-Simulation-Note". I want turn it off by adding option:</p>
  
  <pre><code>--no-show-user-simulation-note
  </code></pre>
  
  <p>But in this case I got error message:</p>
  
  <blockquote>
    <p>Command line option --no-show-user-simulation-note is not understood</p>
  </blockquote>
  
  <p>How can I manage this issue?</p>
