OpenTelemetry net.peer.name attribute is out of date

[JamesNK]

The net.peer.name attribute here is out of date.

address.server is the modern name. See open-telemetry/opentelemetry-specification#3199

Should also add peer.service which is a general name: https://github.com/open-telemetry/semantic-conventions/blob/482cb01c4598429c65dd0b123b30259f41b360cb/docs/general/attributes.md#general-remote-service-attributes

Discussed this with @lmolkova and @jcocchi. Agreed to make this change as HTTP semantic conventions are stable now.
