Serve static assets with NGINX

[c-lliope]

We set up NGINX in order to get LetsEncrypt certificates up and working for our site. Our NGINX configuration is very simple, and proxies all traffic directly to the Rails app, even for static content.

To speed up our static content, we should mount the public directory into the NGINX container and serve it directly.
