Add networking-odl project to StackForge

This repo will be used for development of OpenDaylight drivers necessary for
OpenDaylight to run with Neutron.

The need of setting this repo up is inline with spec proposal [1], where core
elements of the Neutron project are decoupled by the internals of the
technology being supported.
