Use cloud-config-operator to render FeatureGate CR is guest cluster

The dev workflow for OCP operators wanting to use feature gates is

1) change openshift/api
2) bump openshift/api in cluster-config-operator (CCO)
3) bump openshift/api in your operator and add logic for the feature gate

Currently, hypershift requires its bump to openshift/api in order to set the proper feature gates and this is not preferred. It is preferred that the single place where a api bump is required is cluster-config-operator.

Hypershift should use CCO `render` command to generate the FeatureGate CR
