Add Networking-vSphere project to StackForge

This repo will hold the Neutron drivers and agents
necessary to manage vSphere management clusters as
proposed by specifications [1, 2]. Other fully open
source contributions to Neutron support for vSphere
are also welcome, and this is just a start.

The need of setting this repo up is inline with
spec proposal [3], where core elements of the Neutron
project are decoupled by the internals of the
technology being supported.
