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.
