Documentation for Prometheus Plugin and metrics

[oferns]

I cannot generate any metrics. The /metrics endpoint returns 200 but no metrics. I am assuming I am missing configuration but I cannot find any documentation about configuring it or about any in-built metrics.

Sorry, the documentation on this topic is very lacking. I have added a prometheus example for your reference. #2076

The middleware is a new feature added to drogon, now you can't add PromStat as a global middleware like filters. We will make it possible in the future.
