Config headers to not be capitalized

Context

I am consuming a API that have case sensitive header keys.
It is not common to see an case-sensitive header and also is off the specification. But sometimes it is off our control.

What I have in mind is some config to making possible to prevent the capitalize behavior and pass the header without changing it. Something like this:

http = Net::HTTP.new(endpoint.host, endpoint.port)
http.preserve_headers = true

The default behavior will remain the same, the idea is only change the behavior if this config are true.

Some workaround I can do is making a monkeypath to prevent the capitalization, but I thing it make sense to have this configuration.

I can try to implement it, but I want to know if make sense for Net::HTTP.

Start at the Net::HTTP.new entry point and inspect how request headers are currently capitalized. Define the configuration behavior so the default remains unchanged while an enabled option preserves supplied header casing, then verify the existing header behavior and the new option.
