Subject: [PATCH] Update stack.sh for Quantum openvswitch plugin changes

With support for multiple physical networks being added to the Quantum
openvswitch plugin via https://review.openstack.org/#/c/11388/, the
configuration needed to enable either tunneling or VLANs has
changed.

See http://wiki.openstack.org/ConfigureOpenvswitch for configuration
and usage details.
