title: How to debug all parameters on environments in Symfony?
body: <p>I would like to debug my Symfony parameters on specific environments by getting a table with all of them, and their values like:</p>
  <pre><code>Parameter  | prod  | dev  | foo   |
  -----------|-------|------|-------|
  appname    | toto  | titi | tata  |
  isonline   | true  | true | true  |  // Inheritance appears
  firstname  | undef | Bob  | Bob   |  // No values appears
  </code></pre>
  <p>Do you know if there is a feature/bundle/command to do that ?</p>
  <p>It becomes necessary when you get more than 5 environments with different configurations.</p>
