Hello again @posix4e

Thank you for the quick response in last PR.

When I starting prometheus demo, prometheus server(version: 0.20.0) report an error: text format parsing error in line 1: invalid metric name

This PR add a content-type, and fix the error.

For more infomation please refer to https://prometheus.io/docs/instrumenting/exposition_formats/
