Comment 15 for bug 1889396

The Stein backport works as intended. Validated with https://github.com/openstack-charmers/zaza-openstack-tests/blob/master/zaza/openstack/charm_tests/neutron_arista/tests.py , which is a test deploying an OpenStack (including Neutron with this plugin), creating/deleting networks and verifying that the networks appear/disappear on the Arista eAPI.
