Public bug reported:

While there is a VIP port already created and used by other LB
(Amphorea), which in different thread is going to be deleted, and second
thread tries to re-use the same IP address as previous VIP, the OVN LB
sends the update_status_to_octavia() instead fail with driver error.

Example:
https://github.com/openstack/networking-ovn/blob/stable/train/networking_ovn/octavia/ovn_driver.py#L1811

It causes some strange Octavia API behavior.

Example log:

The OVN Octavia provider should do the same as Amphorea provider:
https://github.com/openstack/octavia/blob/master/octavia/api/drivers/amphora_driver/v2/driver.py#L77
