Import a text file in prometheus-format(of HELP and TYPE) to prometheus/sysdig for exposing metrics/

[arjunbakshi245]

I have a metrics endpoint defined and working. However there are some new metrics I want to expose, and these are not available in my local machine. The new metrics are sent to me regularly as an updated text file(in prometheus format). I want to know how should I import the metrics in this text file into the metrics endpoint.
Preferable this maybe done without explicitly parsing this file and registering and reporting metrics from there. I want to know if there is any other feature/option to include these readily structured metrics from the text file directly to sysdig/prometheus agent.
