In addition to the kube_deployment_status_replicas_available metric, it might be quite a good idea to use one or two Prometheus blackbox exporters to check on the availability of https://superset.wikimedia.org

Hmm. It seems that we already have some http blackbox probes defined here in the service catalog:
https://github.com/wikimedia/operations-puppet/blob/production/hieradata/common/service.yaml#L4034-L4036

I specifically intercatpted these in the nginx reverse proxy here:
https://github.com/wikimedia/operations-deployment-charts/blob/master/charts/superset/templates/configmap.yaml#L202-L204

...but maybe that's not a good idea. Maybe we should remove this section and pass them through to the application. What do you think @brouberol @Stevemunene ?

I do think it's a good idea actually
