Nginx internal connection - unix socket

[stefanwerfling]

Check whether an internal connection via Unix socket is possible. Double check beforehand whether this has a performance advantage.

We have the problem that apparently only one server can bind to the Unix sock:

flyingfish_service   | {"level":"error","message":"NginxServer::stderr: 2024/04/12 09:05:07 [emerg] 19#19: bind() to unix:/opt/flyingfish/nginx/socks/127_0_0_1_10443.sock failed (98: Address already in use)","timestamp":"2024-04-12T09:05:08.858Z"}

Unfortunately we cannot list multi http servers on unix, so the ticket is no longer valid.
