Allow forcing polyfill

See original GitHub issue

I found a bug in Chrome that window.fetch does not send cookie when POSTing, even have credentials set (see Issue 490519). So we may have to polyfill chrome as well, at least provide a way to do so.

Currently github/fetch only polyfills UA whose window.fetch is undefined. So it will not polyfill the broken fetch in chrome.

I mean, that’s just not true. We have many examples, including production websites, getting credentials in Chrome. I asked you for a runnable repro case in the Chromium bug and you haven’t provided. I was going to wait until you did so but at this point you’re just spreading false information.

@tjwudi I just tried in Chrome 43.0.2357.65. Both same-origin and include values for credentials: key enable sending the cookie value. I’m sorry, but I can’t reproduce what you’re describing. And in your Chromium bug report, you tried to demonstrate the bug by including sample code, but then you said that the fetch() in the code isn’t native fetch, but your own wrapper that edits the option. You’ll have to provide complete code to demonstrate this issue.
