      Description of problem:

      Our telco-tuned dut pods are not starting in 4.13 with these definitions:
      irq-load-balancing.crio.io: disable
      cpu-load-balancing.crio.io: disable

      31s         Normal    AddedInterface   pod/hw-offload-testpmd   Add eth0 [10.131.0.44/23] from ovn-kubernetes

      11s         Warning   Failed           pod/hw-offload-testpmd   Error: failed to run pre-start hook for container "hw-offload-testpmd": set CPU load balancing: timed out waiting for the condition
      
      Removal of these components will result in a pod starting, but the performance will be significantly degraded.
