Subject: [PATCH] Allow Synapse workers to be used with an external nginx
 webserver

We're talking about a webserver running on the same machine, which
imports the configuration files generated by the `matrix-nginx-proxy`
in the `/matrix/nginx-proxy/conf.d` directory.

Users who run an nginx webserver on some other machine will need to do
something different.
