Neutron.conf is not setup unless q-svc is enabled

In a multi-node environment, a node may have the neutron-
openvswitch-agent running but not the neutron API server.
The agent uses neutron.conf as one of the configuration
files. Devstack sets up neutron.conf only when q-svc is
enabled. Neutron.conf also needs to be configured when
q-agt is enabled.
