PrometheusAgent.spec.image

image defines the container image name for Prometheus. If specified, it takes precedence over the `spec.baseImage`, `spec.tag` and `spec.sha` fields. Specifying `spec.version` is still necessary to ensure the Prometheus Operator knows which version of Prometheus is being configured. If neither `spec.image` nor `spec.baseImage` are defined, the operator will use the latest upstream version of Prometheus available at the time when the operator was released.
