title: Is there a way to validate the broker's SSL certificate in django-celery?
body: <p>I'm using django-celery do connect to a RabbitMQ broker through SSL (with the BROKER_USE_SSL setting). Is there a way to:</p>
  
  <ol>
  <li>Verify the certificate of the broker when the connection is established.</li>
  <li>Configure a client certificate to us to establish the connection.</li>
  </ol>
  
  <p>The RabbitMQ side is working correctly, but I don't know how to configure Celery for this and I haven't found anything in Celery's documentation either. The settings CELERY_SECURITY_KEY, CELERY_SECURITY_CERTIFICATE and CELERY_SECURITY_CERT_STORE look like they could do this, but it seems that they're only used for message signing.</p>
