title: retrofit 2 / okhttp3 clear cookies
body: <p>I'm using retrofit and cookieJar</p>
  
  <pre><code>okBuilder.cookieJar(getCookieJar());
  </code></pre>
  
  <p>Everything works great, but sometimes I want to clear cookies. How can I do it in retrofit or okhttp?</p>
  
  <p>In JavaNetCookieJar are only 2 public methods:</p>
  
  <pre><code>cookieJar.loadForRequest()
  cookieJar.saveFromResponse();
  </code></pre>
