title: Rally: Get user _ref from RallyRestApi object created using ApiKey
body: <p>I created a connection to rally using the ApiKey constructor.</p>
  
  <blockquote>
    <p>Question is how do i find out the User "_ref" associated with this User ApiKey ?</p>
  </blockquote>
  
  <pre><code>rallyRestApi= new RallyRestApi(new URI(host), "myApiKey");
  </code></pre>
  
  <p>I tried following 2 test runs:</p>
  
  <ol>
  <li><p>doing a blank query (i.e. without any setQueryFilter) on User object; it returns me all the users.</p>
  
  <p>QueryRequest userRequest = new QueryRequest("User");
  QueryResponse userQueryResponse = connection.query(userRequest);
  JsonArray userQueryResults = userQueryResponse.getResults();</p></li>
  <li><p>Getting owner from Workspace object  >> This returns me the owner of the Workspace</p></li>
  </ol>
