Forceful Termination of Running Orchestrations

Today, terminate API is an async API. So if there's an instance running and we call /terminate, the framework return with "Accepted". However, in the background if the activity function is taking time, the terminate may take time depending on the activities (Please confirm my understanding here).

I need a way to terminate the orchestration instance forcefully that would stop all the running activity functions forcefully, or have a function "stop" in activity definitions that guide the behaviour of activities in case a forceful terminate is called.

Essentially, an API might look like this /terminate?force=true

该 issue 没有指出文件、测试或入口点。首先追踪 terminate API 以及所描述的后台活动行为；要视为完成，必须确定强制终止契约，包括正在运行的活动应如何处理。
