HPA Issue with CSE 0.7.1 Chart

[pescetto]

When using the v0.7.1 helm chart for cse, we're getting the following error:

error validating data: [ValidationError(HorizontalPodAutoscaler.spec.metrics[0].resource):
unknown field "targetAverageUtilization" in io.k8s.api.autoscaling.v2beta2.ResourceMetricSource,
ValidationError(HorizontalPodAutoscaler.spec.metrics[0].resource): missing required field "target" in io.k8s.api.autoscaling.v2beta2.ResourceMetricSource,
ValidationError(HorizontalPodAutoscaler.spec.metrics[1].resource): unknown field "targetAverageUtilization" in io.k8s.api.autoscaling.v2beta2.ResourceMetricSource,
ValidationError(HorizontalPodAutoscaler.spec.metrics[1].resource): missing required field "target" in io.k8s.api.autoscaling.v2beta2.ResourceMetricSource]

It looks like this change updated the API for HPA, but according to the Kubernetes HPA docs, it looks like the structure was changed from this:

  metrics:
    - type: Resource
      resource:
        name: cpu
        targetAverageUtilization: 60

to this:

metrics:
  - type: Resource
    resource:
      name: cpu
      target:
        type: Utilization
        averageUtilization: 60

Here's another doc from Google GKE showing an example configuration supporting the new conventions.
