Pull Request (PR) description

I want to configure nginx unix socket on SSL vhost. In my case, I have listen_port == ssl_port, selected template does not allow me to configure unix socket.

Hi! Can you add some test in your PR to ensure this new feature is not broken by future evolution/refactoring of the module?

Hey @ymartin-ovh , can you rebase with our master branch? That should fix failing specs.
