@return ClusterTrustBundle allows a pod to access the `.spec.trustBundle` field of ClusterTrustBundle objects in an auto-updating file.

Alpha, gated by the ClusterTrustBundleProjection feature gate.

ClusterTrustBundle objects can either be selected by name, or by the combination of signer name and a label selector.

Kubelet performs aggressive normalization of the PEM contents written into the pod filesystem.  Esoteric PEM features such as inter-block comments and block headers are stripped.  Certificates are deduplicated. The ordering of certificates within the file is arbitrary, and Kubelet may change the order over time.
