RadzenUpload doesn't send cookies

When using a cookie authenticated API scheme with the API on a different domain, RadzenUpload is ineffective because it doesn't post the cookie. Cookie header cannot be added by RadzenUploadUpload headers because, I guess, the browser is stripping it as "withCredentials" is false.

Could we add "xhr.withCredentials = true;" after line 617 so that it does? Or even make it a "WithCredentials" option on the component?

Hi @adrianj,

You can open a pull request with the suggested changes. We will gladly accept it. I think we can do xhr.withCredentials = true by default (without a new parameter).
