Prometheus collector won't work for CRI-O users #156

This doesn't work on OKE (Oracle). You can read more about it here: https://community.replicated.com/t/kubernetes-1-34-short-name-mode-is-enforcing/1591 .

Making it possible to either adjust it, for example like this:

        prometheusCollector:
          image:
            repository: docker.io/prom/prometheus

Or setting the image to docker.io/prom/prometheus (no short name) by default will fix the problem.
