// GetChangeTokenStatusRequest returns a request value for making API operation for
// AWS WAF Regional.
//
// Returns the status of a ChangeToken that you got by calling GetChangeToken.
// ChangeTokenStatus is one of the following values:
//
//    * PROVISIONED: You requested the change token by calling GetChangeToken,
//    but you haven't used it yet in a call to create, update, or delete an
//    AWS WAF object.
//
//    * PENDING: AWS WAF is propagating the create, update, or delete request
//    to all AWS WAF servers.
//
//    * INSYNC: Propagation is complete.
//
//    // Example sending a request using GetChangeTokenStatusRequest.

//    resp, err := req.Send(context.TODO())
//    if err == nil {
//        fmt.Println(resp)
