Exemplars support

Prometheus have added support for Exemplars, which are a technique to allow linking metrics (like histograms buckets) with tracing. The golang client library supports them already https://github.com/prometheus/client_golang/blob/75560f1d20c5e1fd435c0d26b5601843a18dc22b/prometheus/histogram.go#L278 Not really sure...
