Rename neutron-interconnection from openstack/ to x/ namespace

Project neutron-interconnection was officialy in Neutron stadium but as
there was no activity on this project for quite long time and project
actually never got any real implementation done, during the Shanghai PTG
we decided to move it out of stadium to x/ namespace.

Also api-ref for this project is removed from neutron-lib with commit
[1].
