Subject: [PATCH] Add admission controller API to config and externalize
 ADMISSION_CONTROL

Enable the dynamic admission controller registration API by
adding "admissionregistration.k8s.io/v1alpha1" to --runtime-config
to fix problems when starting up local-up-cluster. Also make sure
ADMISSION_CONTROL can be specified externally.

Fixes 47385
