[Bug 2038091] [NEW] [OVN] Manual sync misidentifies Octavia OVN Load Balancer health monitor port and deletes metadata port
Public bug reported:
Versions:
Neutron: Stable/Yoga (from commit cbe514ecf6)
Octavia: Stable/Yoga (from commit 5bf40c89)
OVN: 22.09 - ovn22.09-22.09.0-31.el9s.x86_64
Looks related to https://bugs.launchpad.net/neutron/+bug/2004238,
however the fix from it is already applied.
Doing manual ovn sync:
