The APIs our consumers are using from neutron.db_utils were rehomed into neutron-lib with https://review.openstack.org/#/c/540161/ and will be consumed in neutron with https://review.openstack.org/#/c/565593 This patch switches the applicable imports over to neutron-lib. It also bumps neutron-lib up to 1.14.0 Change-Id: Iaa30aba3cd0f9d2e90fcbd910723f5332e7b454c
