Draft: Resolve "MinIO serviceMonitor/dashboard not working"

Brought in @micah.nagel changes and just needed to add

prometheusOperator: true

Getting dashboards now for the minio pods. From what I can tell metrics: enabled is not used (though we still get prometheus annotations on the pods ??), no servicemonitor is used, and the AdditionalScrapeConfigs is dynamically create/removed now.

see https://github.com/minio/operator/commit/6cf1612e9b64a6b400394ac5f01353953d58fa37

Closes #24 (closed)
