Cinder Lab Setup Added

* Additional node for OpenStack Block Storage (Cinder)
* /vagrant/.controller file keeps track of the public AND private IP for the Controller.  This is used to generate the private IP for Cinder that is used in nova.conf and cinder.conf for the iscsi_ip_address value
* force-yes switch for OpenStack module still present but no longer required.  Will keep them in just in case the Ubuntu\Canonical repo's have a hiccup again.
