title: How to define exceptions for nx-lint?
body: <p>I have a readme file which has docs for the folder, the contained libs and how to use them.</p>
  <p>The readme is not part of any lib and so nx-lint throws this error:</p>
  <pre><code> NX   ERROR  The following file(s) do not belong to any projects:   
      - libs/global/README.md
  </code></pre>
  <p>How can we suppress this error?</p>
  <p>Notes:</p>
  <ul>
  <li>I don't want to move the file into a lib - the current location is correct</li>
  <li>I don't want to add something to the readme that is visible</li>
  <li>Ideally we only suppress this specific error for this file</li>
  </ul>
  <p>I tried to use exclude in the top-level <code>tslint.json</code> like this:</p>
  <pre class="lang-json prettyprint-override"><code>{
    &quot;exclude&quot;: [
      &quot;libs/global/*.md&quot;
    ]
  }
  </code></pre>
