Fake the VIP Go Files service locally

[joshbetz]

The image_downsize filter doesn't fire outside of the production environment because we don't have access to the VIP Go Files service I think we could still run parts of the a8c-files plugin and just disable the parts that interact with the VIP Go Files service itself. It obviously wouldn't be exactly the same -- we'd have to use full size images instead of appending width/height query strings -- but it might make local debugging more useful.

Noting that @johnbillion mentioned this to me recently as something their team would like to see.

@jblz If I'm correct, your team is already doing some work on this, yes?

[jblz]

Hi, @rebeccahum. Yes! We've got it working, but it's in a branch in private repo and it's not likely to get incorporated into the public dev-env on that basis. I'll link to this issue from that PR so they're cross-linked for internal contributors.

I think a good workaround would be an imitation Files Service that lives in dev-env. I would suggest we close this as it may not be the place to track this.
