The current way to publish ORES metrics seems to be the following:

• Metrics are pushed to a statsd endpoint (basically it supports Graphite only)
• For every ores node, there is a local statsd endpoint provided by a prometheus exporter, that in turn offerts an http api to collect metrics (used by the prometheus master nodes)

With the transition to KFServer-based models, we don't really have any metrics. We should figure out if it is possible to add Prometetheus metrics, or similar, so that we'll be able to replicate dashboards like https://grafana.wikimedia.org/d/HIRrxQ6mk/ores?orgId=1&refresh=1m
