title: How to remove sort & direction keys from the pagination links and apply the order specified in controller action
body: <p>I'm using paginator component of <code>paramType</code> is <code>querystring</code>, and specified multiple order in action before taking results from <code>$this-&gt;paginate()</code> as like this</p>
  
  <pre><code>$this-&gt;paginate['order'] = array(
      "field1" =&gt; "Asc",
      "field2" =&gt; "Desc",
      "field3" =&gt; "Asc",
  );
  
  $this-&gt;set('results', $this-&gt;paginate('ModelName'));
  </code></pre>
  
  <p>When i click on page 2 link it's generating a url like <code>?page=2&amp;sort=field1&amp;direction=Asc</code> I want to remove the sort key from query strings and need to fetch the results by applying order i've specified.</p>
