XXXXX.yaml contains an invalid HorizontalPodAutoscaler (openshift 3.11 strict)

I am seeing this error:
```
WARN - web_hpa.yaml contains an invalid HorizontalPodAutoscaler (app-x-hpa) - targetCPUUtilizationPercentage: Additional property targetCPUUtilizationPercentage is not allowed`
```
using flags --openshift --strict -v 3.11.0 on the following yaml construct:
```
apiVersion: autoscaling/v1
kind: HorizontalPodAutoscaler
metadata:
name: app-x-hpa
spec:
maxReplicas: 15
minReplicas: 3
scaleTargetRef:
apiVersion: apps/v1
kind: Deployment
name: app-x-deployment
targetCPUUtilizationPercentage: 60
status:
conditions: []
currentMetrics: []
currentReplicas: 0
desiredReplicas: 0
```
furthermore, the status values are not required, yet --strict fails if they are not defined.

Using kubeval version :
```
15:03 $ kubeval --version
Version: 0.16.1
