title: generate list of quarters betweeen given dates
body: <p>I need to get the list of quarters between the given dates in python.</p>
  
  <p>For example: 
  start_date = March 2012 ,
  end_date = June 2013</p>
  
  <p>Expected output: </p>
  
  <pre><code>['March 2012', 'June 2012', 'September 2012', 'December 2012', 'March 2013', 'June 2013']
  </code></pre>
  
  <p>I checked other threads like <a href="https://stackoverflow.com/questions/33160952/generate-time-series-by-quarter-increment-by-one-quarter">generate time series by quarter, increment by one quarter</a> but my requirement is little different. I need it in the exact same format as mentioned above. </p>
