allow custom stream conf

[klutchell]

Allow a top-level custom stream configuration file to be loaded.

Example /data/nginx/custom/stream.conf that performs DNS load balancing with the upstream block.

server {
    listen 192.168.8.4:53;
    proxy_pass dns_servers;
}
server {
    listen 192.168.8.4:53 udp;
    proxy_pass dns_servers;
}
upstream dns_servers {
    server 192.168.8.8:53 weight=5;
    server 192.168.8.9:53;
    server 1.1.1.1:53 backup;

This type of configuration is not possible with the stream files generated via NPM.
