Motivation
Sometimes, it's useful to wait for graceful shutdown to happen before resuming execution on a task.
This can be of particular interest when we don't have anything to do in a Service's
runmethod but want to make sure some cleanup happens on graceful shutdown.In this scenario, we can achieve this by calling
await gracefulShutdown()inrun(), followed by whatever cleanup we must do.Modification
This PR adds a new
gracefulShutdown()function to theGracefulShutdownsuite.Result
A new
gracefulShutdown()method in theGracefulShutdownsuite.
