socket and stream support

Please add the use of unix://dir/app.socket

and it would be cool to add the use of a different type of stream, using SNI it would be very useful for proxying for the X-Ray reality protocol.
what is there is for something else and it won't work to do it that way

required:
ngx_stream_module
which is in the package - nginx-extras

** example:**

`user nginx;
worker_processes auto;

load_module /usr/lib/nginx/modules/ngx_stream_module.so;

error_log /logs/nginx_error;
pid /var/run/nginx.pid;

events {
worker_connections 1024;
}
stream {
upstream reality {
server xray:12000;
}
map_hash_bucket_size 128;
map $ssl_preread_server_name $sni_name {
example.com reality;
default other;
}
server {
listen 443 reuseport;
proxy_pass $sni_name;
proxy_protocol on;
ssl_preread on;
}
}
`

Start with the issue's ngx_stream_module requirement, nginx-extras package note, and example stream configuration. Determine how Unix socket upstreams and SNI-based stream proxying would fit the project, then define tests or configuration behavior that demonstrate both requested capabilities are supported.
