net-mgmt/promxy: Add new port

Promxy is a prometheus proxy that makes many shards of prometheus appear
as a single API endpoint to the user. This significantly simplifies
operations and use of prometheus at scale (when you have more than one
prometheus host). Promxy delivers this unified access endpoint without
requiring any sidecars, custom-builds, or other changes to your
prometheus infrastructure.
