[Bug 1886962] [NEW] [OVN][QOS] NBDB qos table entries still exist even after corresponding neutron ports are deleted

 

Public bug reported:

When removing neutron ports with qos policy applied, corresponding
entries are not removed from NBDB qos table.

Steps to reproduce:

openstack network qos policy create bw-limiter
openstack network qos rule create --type bandwidth-limit --max-kbps 3000     --max-burst-kbits 2400 --egress bw-limiter
openstack network create internal_A
openstack port create vm1-port --network internal_A
openstack port set --qos-policy bw-limiter <PORT ID>
On this stage 'ovn-nbctl list qos' displays corresponding qos rule of the port
openstack port delete <PORT ID>
Result: port removed from neutron DB - this is OK. But OVN NBDB qos table still displays qos entry for this port:

** Affects: neutron
