Templatize apiVersion and Kind of nats/pod-monitor for GKE compatibility

[Patrick Bennett]

What motivated this proposal?

The current pod monitor spec for nats uses:

apiVersion: monitoring.coreos.com/v1
kind: PodMonitor

yet GKE expects:

apiVersion: monitoring.googleapis.com/v1
kind: PodMonitoring

See: https://cloud.google.com/stackdriver/docs/managed-prometheus/setup-managed

What is the proposed change?

Either provide toggle for openshift vs google that switches both, or allow each to be overridden.

Who benefits from this change?

Any users using Google Kubernetes Engine.
Managed Prometheus is now the default metrics engine for GKE clusters as well.

What alternatives have you evaluated?

No response
