申请证书的时候一直卡在 waiting for record propagation，如下日志：

可以看到是 15:37:32 (CST) 开始申请的，但截止到编辑本 issue 的时间 16:21:52 (CST) 为止，日志一直停在这个位置，且状态一直是 申请中。如果我没猜错的话，必须要等到 16:37:55 (CST) 才能结束，我才能再次尝试？

这期间没有任何停止按钮，一个域名就要等他自己超时半小时，两个就要等一个小时，难道只能干等着吗？为什么不能主动停止？

Please describe the solution you suggest

添加一个停止的按钮，允许用户在证书申请时主动停止申请任务
