fileserver: Add status code override (#4076)
After reading a question about the `handle_response` feature of `reverse_proxy`, I realized that we didn't have a way of serving an arbitrary file with a status code other than 200. This is an issue in situations where you want to serve a custom error page in routes that are not errors, like the aforementioned `handle_response`, where you may want to retain the status code returned by the proxy but write a response with content from a file.
This feature is super simple, basically if a status code is configured (can be a status code number, or a placeholder string) then that status will be written out before serving the file - if we write the status code first, then the stdlib won't write its own (only the first HTTP status header wins).
