How reproducible: Always

Steps to Reproduce:

0. In OCP/Kuryr

1. In the kuryr-controller logs there are many messages with the content:
2021-02-25 13:20:41.954 1 WARNING urllib3.connectionpool [-] Connection pool is full, discarding connection: overcloud.internal.adcubum.com: queue.Full

2. We found Neutron being slow transitioning the ports to ACTIVE and kuryr cni needs to wait for that before completing the CNI ADD requests.

3. Then looking octavia logs in controller-0 (OSP) there is the problem:

Server-side error: "Provider 'ovn' does not support a requested option: Subnet is required for Member creation with OVN Provider Driver". Detail:

During handling of the above exception, another exception occurred:

octavia.common.exceptions.ProviderUnsupportedOptionError: Provider 'ovn' does not support a requested option: Subnet is required for Member creation with OVN Provider Driver

Actual results: kuryr react too slow by assigning new ports in openstack


Expected results: No delays
