See proposal section here https://github.com/aerogear/proposals/blob/master/metrics/prometheus-metrics-endpoints-and-auto-discovery.md#default-visualisations for the inital approach for sourcing Grafana dashboards.

See comment thread here https://github.com/aerogear/proposals/pull/5#discussion_r157767612 for dicussion on auto-discovery of grafana dashboards when a service is provisioned.
Investigate if the discussed approach is possible, preferably showing a proof of concept. See what changes are happening in Grafana 5 upstream, paritcularly around Dashboards from configuration https://github.com/grafana/grafana/issues/9957
