Having trouble using the generateClientV2 if the spec has arguments that are reserved key words.

Hi,

I was having an issue using the generateClientV2 functionality if any of the function arguments were key words. Was able to cut a PR to fix it for the spec I am using. Any risk of sanitizing key word arguments to functions. Have a suggested PR here: Netflix/dgs-codegen#750

Thanks!
