Describe the enhancement

When user cancel a workflow run, the worker process has about 5 mins to response the cancellation and finish what it is doing and exit, otherwise the runner will kill the worker process.

When the process kill happen, we will lost some job/step logs since worker may not finish upload those.

It would be great if the runner can finish upload those logs, since those logs may help us to debug why the cancellation time out and what is hanging.
