ShimV2 has shim.Delete command to cleanup task's temporary resource, like bundle folder. Since the shim server exits and no persistent store is for task's exit code, the result of shim.Delete is always 137 exit code, like the task has been killed. And the result of shim.Delete can be used as task event only when the shim server is killed somehow after container is running. Therefore, dockerd, which watches task exit event to update status of container, can report correct status. Back to the issue #6429, the container is not running because the entrypoint is not found. Based on this design, we should not send 137 exitcode event to subscriber. This commit is aimed to remove shim instance first and then the `cleanupAfterDeadShim` should not send event. Similar Issue: #4769 Fix #6429 Signed-off-by: Wei Fu <fuweid89@gmail.com>
