Allow pods to opt out of PodPreset mutation via an annotation on the pod
An annotation in the pod spec of the form:
podpreset.admission.kubernetes.io/PodPresetOptOut: "true"
Will cause the admission controller to skip manipulating the pod spec,
no matter the labelling.
This is an alternative implementation to pull #44163.

An annotation in the pod spec of the form:
podpreset.admission.kubernetes.io/exclude: "true"
Will cause the admission controller to skip manipulating the pod spec,
no matter the labelling.
The annotation for a podpreset acting on a pod has also been slightly
modified to contain a podpreset prefix:
podpreset.admission.kubernetes.io/podpreset-{name} = resource version
