fix High availability config to be kubernetes.cluster-id

[lydian]

The flink High availability should be using kuberentes.cluster-id instead of high-availability.cluster-id

Here's the settings: https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/deployment/ha/kubernetes_ha/

It seems like in 1.13 is already the same config: https://nightlies.apache.org/flink/flink-docs-release-1.13/docs/deployment/ha/kubernetes_ha/
