Guarantee no requests are running at shutdown event

[LarsSven]

Hello,

I was reading through the Quarkus shutdown guide at https://quarkus.io/guides/lifecycle#graceful-shutdown, and I couldnt'find the full answer to my question. Basically, I have some logic I want to execute for my gRPC server at graceful shutdown, but I want to make sure requests are not running by the time I run the shutdown hook. I don't care about whether my requests return a useful result or just disconnect, but I do care that I run some cleanup code that shuts down a set of containers without a request that was already running spinning up a new container post-cleanup. Is this possible in Quarkus?

Also as a separate question, it says that quarkus.shutdown.timeout is only supported on HTTP (https://quarkus.io/guides/lifecycle#graceful-shutdown), is this correct, or can I also give the application some time to finish all requests when it is a gRPC server?
