Send cancellation

[rakanalh]

Provide a way for send notifications tasks to be cancelled.

How would this be used, and where would you want to cancel it? Shouldn't it be enough to send the celery AsyncResult from send_push_notification?

I need this feature to stop currently executing pushy tasks from the admin... if the notification started sending to all devices, some custom action on the admin interface to cancel (revoke) the sending process would be a nice to have feature. http://docs.celeryproject.org/en/latest/userguide/workers.html#revoking-multiple-tasks
