Currently cancelOnGracefulShutdown hangs forever, if cancellation is not immediately but returns a eventually successful result (test case 1: testCancelOnGracefulShutdownSurvivesCancellation).
If the Cancellation leads to another error than CancellationError, this error is currently not propagated to the user (test case 2: testCancelOnGracefulShutdownSurvivesErrorThrown).
Changes
AsyncGracefulShutdownSequence should never throw as this hides the real errors otherwise
CancellationWaiter should never throw as this hides the real errors otherwise
