The configuration item "conf.neutron.DEFAULT.lock_path" is not
used anymore, we need to override
"conf.neutron.oslo_concurrency.lock_path" to
/var/run/neutron/lock
Verified that in neutron-l3-agent-controller-0
and nova-compute-controller-0, not see lots of errors anymore.
Router update finished in neutron.agent.l3.agent
