Cannot specify admin.type as NodePort

When specifing admin.type as NodePort, the following error occurred:

Error: UPGRADE FAILED: failed to create resource: Service "kong-gateway-admin" is invalid: spec.clusterIPs[0]: Invalid value: "None": may not be set to 'None' for NodePort services

Hi @aldredb 👋

The reason for this is that we set None as the default ClusterIP regardless of the type of the Service. #961 should fix this.
