title: Writing a list of dictionaries directly to S3 as csv
body: <p>I have a list of dictionaries like 
  <code>temp_dict = [{'id':'1', 'name':'john'},{'id':'2', 'name':'jake'},{'id':'3', 'name':'jacob'}]</code> 
  Is there a way using which I can directly write this dictionary as a csv file (pipe delimited) onto S3. I do not want to create a csv file on my local from this list and then copy that to S3.</p>
