[Bug 1681758] [NEW] nova-lxd driver does not work with neutron firewall disabled

[James Page]

Public bug reported:

In a deployment where the firewall is disabled in the neutron-
openvswitch-agent (don't ask); the agent switches to using non-hybrid
ports (no bridge required to apply security group rules).

In this configuration, neutron will expect the tap device to have been
plugged directly into the br-int bridge prior to attempting networking
binding; however the nova-lxd driver does not do this, so binding fails
and instance launch errors after the network binding event times out.
