Local (DMZ) URL for gogs workers (such as ssh update) accessing web service. In
most cases you do not need to change default http://localhost:HTTP_PORT/. You
may need to alter it only if your ssh server node is not the same as http node,
eg. running behind proxy on different node than web server.

                     --- 80 public port -> 8080 -- web server node
                    /
    public proxy --<
                    \
                     --- 22 public port -> 10022 -- ssh server node

This option is not intended to be accessible via web GUI settings, since it is
unlikely someone needs to change it to somethings else than default
http://localhost:HTTP_PORT/ which should work for most of the cases.

But this should land into the documentation somewhere.
