Neutron-neutron interconnection

[Thomas Morin]

Today, to realize connectivity between two OpenStack clouds (e.g. two distinct OpenStack deployments, or two OpenStack regions, for instance) some options are available, such as floating IPs, VPNaaS (IPSec-based), and BGPVPNs.

However, none of these options are appropriate to address use cases where all
the following properties are desired:

* interconnection consumable on-demand, without admin intervention (possible with floating IPs, VPNaaS, but not with the BGP VPN interconnections API extension)

* have network isolation and allow the use of private IP addressing end-to-end (possible with VPNaaS, and BGP VPN interconnections, but not with floating IPs)

* avoid the overhead of packet encryption (possible with floating IPs, and BGP VPN interconnections, but by construction not with VPNaaS)

The goal of this RFE is to propose a solution to provide network connectivity
between two or more OpenStack deployments or regions, respecting these
constraints.

    Update Neutron-Neutron Interconnections

    - Move specification for Neutron-Neutron Interconnections RFE for
      implementation in Stein release,
    - Remove redundant states from lifecycle FSM,
    - Add remote_interconnection_id attribute to interconnection resource,
    - Minor update in API exchange example.

Due to lack of activity neutron-interconnection project was some time ago moved from Neutron stadium to the x/ namespace.
So I think that we can close this RFE as "abandoned" now.
