exporter/prometheus

Is your feature request related to a problem? Please describe.

If I send exponential histograms that contain exemplars to the collector, the collector can receive them (I can see them in the debug exporter output) but the Prometheus exporter does not have exemplars on its output (it has the native histogram but without exemplars).

Describe the solution you'd like

Add Exemplars support for native Prometheus histograms in prometheusexporter

Describe alternatives you've considered

N/A
