Added Quantum(Neutron)

Added Quantum(Neutron)

Added an OpenStack Network Services (Quantum\Neutron) node to the C2OS Stack.  A client node is also defined

Implements: c2os/cookbook

NOTE: Total RAM required on Host machine is 8 GB minimum.  To save on usage, you may want to make the following changes to the Vagrantfile:
1. Remove the 'client' entry from the nodes hash
2. Decrease the RAM requirement for Nova (compute) to 2048 instead of 3128
