### NamespaceLifecycle
This plug-in enforces that a `Namespace` that is undergoing termination cannot have new objects created in it,
and ensures that requests in a non-existent `Namespace` are rejected.
and ensures that requests in a non-existent `Namespace` are rejected. This plug-in also prevents deletion of
three system reserved namespaces `default`, `kube-system`, `kube-public`.
A `Namespace` deletion kicks off a sequence of operations that remove all objects (pods, services, etc.) in that
namespace. In order to enforce integrity of that process, we strongly recommend running this plug-in.
