There was a problem hiding this comment.
I would prefer not to hard-code the default socketAddr like this - SocketAddr::from_str("0.0.0.0:9000).
Even if it's functionally the same as calling metrics_exporter_prometheus::PrometheusBuilder::new() now, if the defaults in PrometheusBuilder change in the future, we would need to manually perform the update.
Ideally, we keep the old syntax if ip is not specified here. Maybe with a match case.

Makes perfect sense, will update after my work shift

Motivation
Add an snarkOS cli option to configure the listening host and port of the metrics exporter.
Although I think listening to 127.0.0.1 by default should be a better default value, I kept 0.0.0.0 to not break existing users (the previous default was hardcoded
0.0.0.0:9000). Same for the cli option name, although it's different from rest and cdn options. Lemme know if breaking backwards compatibility is acceptable there.Test Plan
