Resolver: cancelable resend timer event. It is safe because re-sending still works during graceful shutdown as long as resolving takes place (and resolve tasks set their own timeouts that are not cancelable). Also, the new ctx->cancelable flag can be set to make resolve task's timeout event cancelable.
