title: List installed files of a package?
body: <p>I've done my homework: searched, tried and read conda documentation. However, I could not find the answer to this seeming common and simple task: List files that belong to an installed package. How do I do that?</p>
  
  <p>My conda version: <code>conda 4.3.30</code></p>
  
  <p>I've looked at <code>list, info, search, and package</code> subcommands.</p>
  
  <p>My use cases for this: </p>
  
  <ol>
  <li><p>When a package 'A' installed another package 'B' as its dependency. But B has a bug, or the installation somehow broken, I  want to check which files B installed.</p></li>
  <li><p>An extended use: when commands of A calls some command <code>b</code> of B, but I don't know the exact name of B. A 'reverse' search based on <code>b</code> to find out B and lets me read more about it. </p></li>
  </ol>
