OK, got it. What you want to do is actually not in Nova but rather in 
the Neutron SFC and Tacker projects:

https://github.com/openstack/networking-sfc
https://github.com/openstack/tacker

Go ahead and read up on those two projects and get a feel for how they 
are structured. You can head over to Freenode IRC on the 
#openstack-neutron channel to chat about Neutron service function 
chaining. The #tacker channel has folks interested in NFV orchestration 
and should be able to help you out.

All the best,
