Bug description:
[Impact]
Backport fix to Focal/Ussuri so that neutron-ovn-db-sync-util does not trip up when it finds ovn ACL table entries with a "label" column that does not exist in neutron db.
[Test Plan]
* Deploy Openstack Ussuri
* Upgrade OVN to 22.03 (https://charmhub.io/ovn-chassis/configure?channel=22.03/stable#ovn-source)
* Create a network with security groups
* Create an instance using this network so that ports get tied to SGs
* Go to neutron-api unit (neutron-server) and do the following
* cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.no_keystone_authtoken
* remove "auth_section = keystone_authtoken" in the [nova] section of neutron.conf.no_keystone_authtoken
* run 'neutron-ovn-db-sync-util --config-file /etc/neutron/neutron.conf.no_keystone_authtoken --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --ovn-neutron_sync_mode repair'
* the above should not produce any errors like the following:
RuntimeError: ACL ... already exists
[Regression Potential]
there is no regression potential expected with this patch.
--------------------------------------------------------------------------
OVN introduced a new column in ACL table. The column name is label and
when running db-sync script, we compare ACL generated by the ovn mech
driver from Neutron DB with the actual ACLs in the OVN DB. Because of
the new label column, everything seems like a new ACL because the
column differs to what Neutron generated. Thus the script attempts to
create a new ACL that already exists.
