HttpConfiguration: add option to pass QueryParams

Summary

We have an issue with passing cookies in request made by 3dtiles (or any object but it's the case we are testing rn). We did try to use the httpConfiguration but because our server need the cookies to be in a the header in a Cookie key we can't use that method as it's a reserved keyword for most browsers. We can also directly pass the cookies as querry params behind the url but we didn't find any proper way of doing this without it beeing hacky. Is there anything else we could try to make it work? Or would this need some changes to the source code?
