    Description

      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    Scheduled        pod/dpdk-testpmd   Successfully assigned default/dpdk-testpmd to ostest-zh6lq-worker-0
      31s         Normal    AddedInterface   pod/dpdk-testpmd   Add eth0 [10.131.0.44/23] from ovn-kubernetes
      21s         Normal    Pulled           pod/dpdk-testpmd   Container image "registry.redhat.io/openshift4/dpdk-base-rhel8:v4.10.0-5" already present on machine
      21s         Normal    Created          pod/dpdk-testpmd   Created container dpdk-testpmd
      11s         Warning   Failed           pod/dpdk-testpmd   Error: failed to run pre-start hook for container "dpdk-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.
