[stable/cluster-autoscaler] Update tags to match documentation (#15812)

Prior to this change, the cluster tag had prefix `kubernetes.io`. The upstream
documentation was updated in June 2018.

This change updates the cluster tag prefix to the correct value, `k8s.io`.

Since this is a breaking change, bump the major version of the chart.
