title: ChromeDriver opens sites only with valid SSL certs
body: <p>There are two instances of the same site, only difference is, that one uses a valid, another one uses an invalid <code>HTTPS/SSL certification</code>. I tried to open both in headless <code>ChromeDriver 2.31</code> and found it opens site only with valid <code>SSL</code> certification. </p>
  
  <pre><code>&lt;chromepath&gt; --headless --remote-debugging-port=9101 --disable-gpu &lt;siteurl&gt;
  </code></pre>
  
  <p>Code above opens a site <a href="https://chrome-devtools-frontend.appspot.com/serve_file/identification_number" rel="noreferrer">https://chrome-devtools-frontend.appspot.com/serve_file/identification_number</a> with a preview from the given website.</p>
  
  <p>I use this to ignore certificate problems, but I get the same blank page for this site in <code>ChromeDriver</code>.</p>
  
  <pre><code>caps.setCapability("chrome.switches", Arrays.asList("--ignore-certificate-errors"));
  </code></pre>
