Kevin Benton c76164c058 Move conntrack zones to IPTablesFirewall
The regular IPTablesFirewall needs zones to support safely
clearly conntrack entries.

In order to support the single bridge use case, the conntrack
manager had to be refactored slightly to allow zones to be
either unique to ports or unique to networks.

Since all ports in a network share a bridge in the IPTablesDriver
use case, a zone per port cannot be used since there is no way
to distinguish which zone traffic should be checked against when
traffic enters the bridge from outside the system.

A zone per network is adequate for the single bridge per network
solution since it implicitly does not suffer from the double-bridge
cross in a single network that led to per port usage in OVS.[1]

This had to adjust the functional firewall tests to use the correct
bridge name now that it's relevant in the non hybrid IPTables case.
