proposal: net/http: add accessor for number of listeners and connections

[erwiese]

Hi,
running a http/server it would be helpfully to know the count of listeners and connections, for monitoring reasons. The server already has the fields listeners and activeConn. What about adding methods like GetCurrentListenersCount and GetActiveConnectionsCount?

I think it is possible to track listeners externally before calling Serve and track connections using https://pkg.go.dev/net/http#ConnState callback

Yes, but why should I do that work, if the information is already available and only the accessor is missing.
