优雅停机大概率出现，优雅中断线程后，状态没有同步到admin

Please answer some questions before submitting your issue. Thanks!

Which version of XXL-JOB do you using?

目前在master、2.1.0版本都验证了此问题

Expected behavior

graceful shutdown 调起 XxlJobExcutor destroy 方法 所有任务线程执行结果推到admin后再关闭回调线程

Actual behavior

JobThread大概率在TriggerCallbackThread销毁后，才添加失败消息到TriggerCallbackThread队列中，导致执行结果丢失

23:12:11.919 logback [xxl-job, executor TriggerCallbackThread] INFO  c.x.j.c.thread.TriggerCallbackThread - after stop callback queue size 0
23:12:11.919 logback [xxl-job, executor TriggerCallbackThread] INFO  c.x.j.c.thread.TriggerCallbackThread - after last callback queue size 0
23:12:11.920 logback [xxl-job, executor TriggerCallbackThread] INFO  c.x.j.c.thread.TriggerCallbackThread - >>>>>>>>>>> xxl-job, executor callback thread destory.
23:12:11.920 logback [Thread-8] INFO  c.x.j.c.thread.TriggerCallbackThread - >>>>>>>>>>> xxl-job, executor retry callback thread destory.
23:12:11.921 logback [Thread-9] INFO  com.xxl.rpc.remoting.net.Server - >>>>>>>>>>> xxl-rpc remoting server stop.
23:12:11.922 logback [Thread-19] INFO  c.x.j.c.thread.TriggerCallbackThread - >>>>>>>>>>> callback queue items [HandleCallbackParam{logId=2789, logDateTim=1567091528922, executeResult=ReturnT [code=500, msg=web container destroy and kill the job. [job running，killed], content=null]}]

Steps to reproduce the behavior

分支：https://github.com/WEIZIBIN/xxl-job/tree/issue_graceful_shutdown_callback_lose

添加了容器优雅停机，线程回调前后的日志

1.启动xxl-job-admin 2.启动xxl-job-executor-sample-springboot 3.手动触发DemoJobHandler任务执行 4.在执行过程中，优雅中止xxl-job-executor-sample-springboot进程

进程停止后，该任务大概率处于执行中的状态

有结论吗？？我也模拟了这样的情况。任务处于运行状态

目前版本是有这种情况，解决方案可以参考我的MR https://github.com/xuxueli/xxl-job/pull/1104
