title: Django Admin Remove default save message
body: <p>I have added this extra message in my model admin and basically i want to remove the default one. Is there someone that can help me to do this?</p>
  
  <p>my actual message:</p>
  
  <pre><code>def save_model(self, request, obj, form, change):
          # add an additional message
          user = request.user
          messages.info(request, "Dear " + str(user)+ " "+ " please note that your parking plot has been reserved")
          super(ParcareModelAdmin, self).save_model(request, obj, form, change)
  </code></pre>
  
  <p>The default one kinda sucks!</p>
  
  <p>Thank you!</p>
