[Foundation] Allow to ignore the use of cookies in the NSUrlSessionHanlder #7659
Description
After landing #7654 we would like to allow users to not use cookies and match the Android HttpHandler so that we have platform parity.
In our case, we have to make sure that we do not use any of the 'CookieContainers' in iOS, that means ignore the managed CookieContainer if it has been set and ignore the cookies from the server of the native CookieContainer.
