Description

Once we support services offline dynamically, we need to have a discuss about how to use it by users.

Now we start/stop Linkis in scripts, maybe we can provide a another grayscale_update.sh to users.

Or any other ideas about this?

grayscale_update.sh

Yes, it is best to provide a graceful stop shell script, enter the service name to start a graceful stop. Only the entrance service needs to wait for the end of the tasks before stopping. Other services can exit by waiting for a config time (eg: 1m) after going offline.
