PLUMgrid plugin supports Quantum Core V2 APIs over an infrastructure running PLUMgrid Network Virtualization Platform. The plugin will interact directly with the Hypervisor layer to provide all the networking functionality requested by Quantum APIs. It will be based on a controller-mode implementation were all resources state will be controlled and handled by the plugin. Implements: blueprint plumgrid-quantum-plugin Change-Id: I6bc8d32b83982e10f661913e85494468cf10e0e2
