server_address

[combro2k]

I found no possibility to keep 'server_address' empty as a option.
We use dual stack networking (IPv4 and IPv6). Now it's default set to '0.0.0.0' but I want it
to be empty. I can try to adjust the manifest / template to allow this or if there is a better approach to this
englighting me :-)

Thank you in advance ✌️
