Preserve backward compatibility with OVS hybrid plugging
In Liberty and before, the Neutron server never had to be
configured with a firewall driver for the OVS hybrid IPtables filtering
bridge to work. However, in Mitaka, some logic snuck in[1] that made it
so if the driver was not defined, the hybrid plugging would be disabled.
This essentially broke anyone upgrading from Liberty to Mitaka who
was using OVS and did not have the firewall driver configured on the
server.
This patch adjusts the default if the driver is not defined on the
server to automatically set hyrbid plugging to true to preserve the
Liberty behavior.

Title:
mitaka now requires firewall driver in neutron server conf or hybrid
agents break
Status in neutron:
Fix Released
Bug description:
Change I13e5cda8b5f3a13a60b14d80e54f198f32d7a529 added the OVS
firewall driver. However, the logic that determined which VIF details
to pass to Nova for hybrid plugging required that the firewall driver
be set on the server side, which was not previously a requirement.
This means that deployments upgrading from Liberty to Mitaka with
agents using the OVS hybrid driver will break if the server is not
configured with the firewall driver.
