Package runtimeclass contains an admission controller for modifying and validating new Pods to take RuntimeClass into account. For RuntimeClass definitions which describe an overhead associated with running a pod, this admission controller will set the pod.Spec.Overhead field accordingly. This field should only be set through this controller, so vaidation will be carried out to ensure the pod's value matches what is defined in the coresponding RuntimeClass.

RuntimeClass is an implementation of admission.Interface. It looks at all new pods and sets pod.Spec.Overhead if a RuntimeClass is specified which defines an Overhead. If pod.Spec.Overhead is set but a RuntimeClass with matching overhead is not specified, the pod is rejected.
NewRuntimeClass creates a new RuntimeClass admission control handler
