SGX Admission webhook was quickly forked from FPGA's implementation. After a bit of thinking, it turns out leader election and metrics are not necessary for a (idempotent) webhook-only functionality. For FPGA Admission webhook, the metrics isn't correctly set up so it's better to disable the functionality. Leader election is kept but the flag name is renamed to align with "kubebuilder v3 functionality" similar to how we changed it to the operator as well.
