描述 / Description

As the title says.

[0x5459]

暂停的线程可以重置状态，比如直接 aborted

当前版本支持此功能

经过测试，在等待执行实际任务 (可能由于并发控制导致等待) 的封装线程无法修改状态

hi, I see that it's not closed so I have 2 ideas:

1. Maybe it could be possible to add pause not only before next stage but with any stage which can be specified? or
2. If worker is sealing I would like to stop it gently for maintenance instead of killing task but I can't. After cli "stop" the worker will finish tasks which are running and stop new jobs with "idle" stage.
