Description
Even when we have description in camel-micrometer, then I do not see them in prometheus exporter (via camel-quarkus).
A sample output is here, where the HELP only have human description for JVM metrics (not from Camel)
# HELP CamelExchangesTotal_total
# TYPE CamelExchangesTotal_total counter
CamelExchangesTotal_total{camelContext="ChaosMonkey",routeId="route2",serviceName="MicrometerRoutePolicyService",} 19.0

# HELP process_start_time_seconds Start time of the process since unix epoch.
# TYPE process_start_time_seconds gauge

I am not sure if we need to do something more special in camel-micrometer. But it would be good to dive into the prometheus exporter from quarkus to track in the code how this works, so we can find out how.
