-- Deletes a subscription. If the subscription requires authentication for deletion, only the owner of the subscription or the topic\'s owner can unsubscribe, and an AWS signature is required. If the 'Unsubscribe' call does not require authentication and the requester is not the subscription owner, a final cancellation message is delivered to the endpoint, so that the endpoint owner can easily resubscribe to the topic if the 'Unsubscribe' request was unintended.
