Subscription Deactivate

To implement the Subscription deactivate API using the SDK, implement the abstract method processSubscriptionDeactivate from the PurchaseServlet:

/**
* Process a subscription deactivation based on the request and returns the response to
* whether or not the request succeeded.
 *
 * @param request
 * the request object with information about the subscription
 *
 * @return a SubscriptionDeactivateResponse object
 */
 public abstract SubscriptionDeactivateResponse
processSubscriptionDeactivate(SubscriptionDeactivateRequest request);
