What?

Backport of #5815 to the v1.x branch for the v1.8.0 release.

Warns when http.get or http.head are invoked with extra unexpected arguments. These methods only accept (url, params), so any additional positional arguments are silently ignored — this change logs a warning to help users catch mistakes (e.g. passing a body argument by analogy with http.post).

Credit to external contributor @moko-poi for the original change.

Why?

http.get and http.head previously accepted and silently discarded any extra arguments, which made it easy to write subtly broken scripts (for instance, attempting to pass a body to http.get as if it were http.post). Emitting a warning surfaces the mistake to the user without breaking existing scripts.
