title: Logging requests to django-rest-framework
body: <p>For debugging purposes, I would like to use Django's logging mechanism to log each and every incoming request when it "arrives" at django-rest-framework's doorstep.</p>
  
  <p>Djagno offers logging of its requests (only "warning" log level and above) in the following manner (from LOGGING section in settings.py):</p>
  
  <pre><code>'django.request': {
          'handlers': ['mail_admins'],
          'level': 'ERROR',
          'propagate': False,
   },
  </code></pre>
  
  <p>I'm looking to achieve something like this (notice: log level is DEBUG):</p>
  
  <pre><code>'rest_framework.request': {
          'handlers': ['logfile'],
          'level': 'DEBUG',
          'propagate': False,
   },
  </code></pre>
  
  <p>Is there a way I can do that <strong>without</strong> embedding a logger in to DRF's source code?<br>
  Is there maybe some sort of "Logging Backend" option in DRF I'm not aware of?</p>
