mintmaker: add controller config for stone-stg-rh01

Add cluster-specific configuration for the stone-stg-rh01 staging
environment to enable Kite integration:

- Create config.json to enable Kite integration and add the API URL
- Add kustomization.yaml that generates a ConfigMap from config.json
- Add patch to mount the config as a volume at /etc/mintmaker
