Expose the addr bit of prometheus' start_http_server() in the config #59
Description
Activity
prometheus_client.start_http_server's first argument seems to be specifically a port as an integer, not an address? The second argument isaddr, making that configurable might be usefulAs for renaming config fields, the config update system exists specifically to support legacy field names without any fallbacks in the actual code.
Hmm, indeed – seems like we've been misusing it for quite a while, and it's been working due to a happy accident more than anything else...

listen_portbeing passed on toprometheus.start_http_servermakes it a whole listen_address, rather than just a port, making configs look confusing when you actually need not-just-a-port in there.Perhaps it'd be worth to rename it, keeping the existing one as a deprecated alias for a while?metricsin the configuration only exposesportas a configurable, making it tricky to listen on non-standard addresses if needed.
