feat: add prometheus endpoint providing basic request metrics (#404)
Browse files Browse the repository at this point in the history 
This patch adds basic prometheus metrics. The prometheus metrics are exposed at the default prometheus exporter port 9000 and is configurable with:

```
 serve:
   prometheus:
     port: 9000
     host: localhost
     metrics_path: /metrics
```
