directly write config rather than using nginx::config::vhost::proxy
directly write config rather than using nginx::config::vhost::proxy

nginx::config::vhost::proxy is not a great fit here, as it does too much:

* google analytics location
* try_files
* proxy_set_header Host $http_host

it felt simpler to directly write our own config here. sadly this also means doing our own nginx::log too
