To make task.Delete retriable, this patch caches the delete result in memory after the shim successfully deletes the task. If a later shutdown attempt fails, a subsequent Delete retry can complete cleanup and return the cached exit information. If containerd restarts after deleting the task, the in-memory cache is lost, and containerd will publish TaskExit and TaskDelete events again to subscribers. Currently, the exit status returned by shim-delete is always 137. In a follow-up, containerd-shim-runc-v2 should store the actual exit status in the state directory, so that shim-delete can reuse it instead of returning a hard-coded value.
