Looks the commit changes deprecated some configuration under neutron.conf:

https://review.openstack.org/#/c/172810/

But in neutron code, it is still adoption as below. Instead of using [nova] section 'admin_auth_url' or 'admin_username' etc.
CONF.nova_admin_auth_url
CONF.nova_admin_username
CONF.nova_admin_password
CONF.nova_admin_tenant_id
CONF.nova_admin_tenant_name

https://github.com/openstack/neutron/blob/master/neutron/common/config.py#L116
Still need in:
https://github.com/openstack/neutron/blob/master/neutron/notifiers/nova.py#L85

Deprecating the options for nova_admin* options will make neutron fail to notify nova for event and could lead VM spawn failure when vif_plugging_is_fatal=true in nova.conf
