Serve: Add Brotli support

[totsteps]

Since Brotli support is merged in node-12, is it possible to add support for it?

For reference:

Hi @totsteps

The serve cli is not intended to use for production applications.

Instead you can deploy your application to ZEIT Now by connecting your Git Repository in couple clicks. Then each time you git push it will deploy!

You get Brotli, Gzip, and many other features automatically.

Try this: https://zeit.co/import/git
