update stack.sh due to quantum changes
update stack.sh due to quantum changes

The following git commit a86c31ba1544528cd8473896076e8b1b4ef14bce
changes the following variables in ovs_quantum_plugin.ini from
(enable-tunneling, local-ip) to enable_tunneling, local_ip).
Therefore the quantum configuration section of stack.sh needs
to also update these variable names.

Fixes bug 1015333

Removes the logic used for plugins.ini which is no
longer needed and adds a mv to copy policy.json

Fixes bug 1015418
