I'm not sure what you mean by zero network config. Do you mean you want to set up the 
tap interface entirely on the host, along with a static IP, and then the container simply 
attaches to that tap device when it boots? I guess that's possible.

Can I ask what you're trying to achieve in terms of this network setup? Are you just after 
straight-forward internet connectivity, or are you planning to filter packets going in and 
out of the container? For the simple usecase, I think you can simply use the normal host 
interface from inside the container, though you can't modify it.
