Comment 0 for bug 1958561

When using creating a fully populated LB with ovn as provider, the listener/pools will stuck in PENDING_CREATE STATE.

I Haven't tested what the result for other Octavia provider as I only have OVN in my environment.

Steps to reproduce:

```
curl -i -X POST -H "Content-Type: application/json" -H "X-Auth-Token: $OS_TOKEN" -d '{"loadbalancer":{"admin_state_up":true,"listeners":[{"name":"http_listener","protocol":"TCP","protocol_port":80}],"vip_subnet_id":"SUBNET_ID","provider":"ovn","name":"best_load_balancer","tags":["test_tag"]}}' https://XXXXXXXXXXXXX:9876/v2.0/lbaas/loadbalancers
```

```
openstack loadbalancer listener show http_listener

| timeout_member_connect | 5000 |
| timeout_member_data | 50000 |
| timeout_tcp_inspect | 0 |

| allowed_cidrs | None |
| tls_ciphers | None |
| tls_versions | None |
| alpn_protocols | None |

```

The listener will remain in PENDING_CREATE state forever.
