AMP headers upfront

[maxime-michel]

I now get the headers I added to server.js, but not those in process.js. This isn't my area of expertise but I'm afraid it might be too late to send headers at that point.

Let's do it upfront like in this example: https://github.com/ampproject/amphtml/blob/ee2dea74e954ceaf5c284bfbfb2f81416858fa9a/build-system/test-server.js#L26

Headers make more sense in the same place anyway. Sorry for the back and forth but I don't know how to run this locally, and I've never debugged JS anyway.

Why have you removed the tests?

[maxime-michel]

Because sadly the relocation of the logic from process.js to server.js means this is not as easily covered. In the scope of the process controller, the mock response will no longer see calls to headers, as this is done upfront. I don't see any other place where the tests could fit, I actually don't see any test for methods in server.js. In the end the logic I'm adding there is pretty minimal, though, isn't it?

Let's try this and see if it works? I've just given it a new try but I don't see any test class in which headers could be inspected. We can always add tests later if needed.

Sorry, this went off my radar. Let's give this a try, merging now.
