This is related to Octavia issue
https://storyboard.openstack.org/#!/story/2008254
When the OVN Octavia Provider driver calls into octavia-lib to update
the status of a loadbalancer, for example, the code in
helper:_update_status_to_octavia() it might fail:
DEBUG ovn_octavia_provider.helper [-] Updating status to octavia: {'listeners':

This is failing because the listener associated with the loadbalancer
was not found, it's DB transaction was in-flight. That's the related
Octavia issue from above, but a fix for that will not solve the problem.
A side-effect is this listener is now "stuck":
$ openstack loadbalancer listener delete 7033179d-2ddb-4714-9c06-b7d399498238
Load Balancer 2cc1d429-b176-48e5-adaa-946be2af0d51 is immutable and cannot be
updated. (HTTP 409) (Request-ID: req-0e1e53ac-4db9-4779-b1f3-11210fe46f7f)
The provider driver needs to retry the operation, typically even the
very next call succeeds.
