Comment 8 for bug 1465440

In Neutron side, 'shared' attribute for firewall has no effect, so I don't think we need any change in DB operation. We can keep the current implementation as-is.

In Horizon side, we should drop 'shared' attribute from FirewallsTable in dashboards/project/firewalls/tables.py
because it has no effect and 'shared' attribute is invisible to end users.

In neutronclient, it is better to drop --shared flag because 'shared' attribute is not supported by the design decision.

From the above reason, I will add neutronclient and horizon to the affected projects.
