llng-fastcgi-server: Allow to listen on TCP
My use case: I want to use LemonLDAP with the Kubernetes Ingress controller for nginx using auth_request.
Best practice on Docker is to have only one purpose per container. i.e one nginx container, and one llng-fastcgi-server container.
NB: I know that I can use
--plackOptions='--listen=:1234' but I don't like it.
