      Description of problem:

      Pod requesting a secondary OVN Kubernetes network does not start.

       

      Version-Release number of selected component (if applicable):

      OCP 4.14.0-0.nightly-2023-12-08-072853

       

      How reproducible:

      Always

       

      Steps to Reproduce:

      1. Create a cluster using cluster bot `launch 4.14`

      2. Create a NAD of type `ovn-k8s-cni-overlay`

      3. Request the network on a Pod

       

      Actual results:

      The Pod does not start. The CNI invocation fails with "failed to get pod annotation: timed out waiting for annotations: context deadline exceeded"

       

      Expected results:

      The Pod starts.
