/*TODO:It is still possible that cri-containerd crashes after we teardown the network, but before we remove the network namespace.
In that case, we'll not be able to remove the sandbox anymore. The chance is slim, but we should be aware of that.
In the future, once TearDownPod is idempotent, this will be fixed.*/
