This function is only invoked when task has been deleted. so, it's probably not that case you mentioned.
Maybe we should keep that container only if it fails to delete container.

no... task delete will append defer function after NewTask success.
After setting to nil upon successful deletion, may encounter the leak you described in the issue #8981, regarding the "not found" error.

I think we should add failpoint test case to verify it. We probably need to check task service as well.

Fix #12344
when executing NewTask in the
podsandbox run, it may fail for various reasons, like timeout, ctx cancle .etc, and the shim process has already started.During the defer cleanup, cleaning up the podsandbox.container only deletes the data in the store and cannot guarantee that the task is properly deleted.
Therefore, it is necessary to retain the podsandbox.container, And task can be actively cleaned up through shutdown api. But the invocation of the task depends on the container information, so keep podsandbox.container even if cleanup done.
There is no guarantee that the NewTask operation is atomic. A failure does not mean that resources have been completely cleaned up. Therefore, it is reasonable to delegate cleanup to the upper caller
