3 of the 4 original issues in the first post are now fixed, and the one that isn't is addressed by a separate bug report:
1. NetworkNotFound: fixed by the introduction of _create_ha_interfaces_and_ensure_network
2. IpAddressGenerationFailure: https://bugs.launchpad.net/neutron/+bug/1562887
3. DBReferenceError: Opened a separate bug, https://bugs.launchpad.net/neutron/+bug/1533460, and fixed by https://review.openstack.org/#/c/260303/
4. HA Network Attribute Error: fixed by the introduction of _create_ha_interfaces_and_ensure_network
I think this bug can be closed.
