title: Making direct gremlin queries from gremlin-python
body: <p>I've encountered several issues with gremlin-python that aren't such in pure gremlin:</p>
  
  <ul>
  <li>I can't directly select a given vertex type (g.V('customer')) without iterating over all vertices (g.V().hasLabel('customer'))</li>
  <li>I get "Maximum Recursion reached" errors from Python. The same query in gremlin works smooth and fast</li>
  <li>The ".next()" command works really slow in gremlin-python while in gremlin takes 1 sec</li>
  </ul>
  
  <p>So, from Python/gremlin-python, I would like to be able to make a pure gremlin query to the server and directly store its result in a Python variable. Is that possible?</p>
  
  <p>(I'm using gremlin-python on Apache Zeppelin if that matters)</p>
