fix: HPA target (#361)

Fixes an issue with HPA autoscaling/v2:
* HorizontalPodAutoscaler.autoscaling "reflector" is invalid: [spec.metrics[0].resource.target.type: Required value: must specify a metric target type, spec.metrics[0].resource.target.type: Invalid value: "": must be either Utilization, Value, or AverageValue, spec.metrics[0].resource.target.averageUtilization: Required value: must set either a target raw value or a target utilization]
