      Description of problem:

      addon-agent and proxy-agent containers in pod cluster-proxy-proxy-agent-xxxx  are not pinned to reserved management cores.
      klusterlet container in pod klusterlet-xxxxx is also not pinned to reserved management cores.
      

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

      oc get clusterversion
      NAME      VERSION       AVAILABLE   PROGRESSING   SINCE   STATUS
      version   4.13.0-rc.2   True        False         5d4h    Cluster version is 4.13.0-rc.2
      

      How reproducible:

      Always

      Steps to Reproduce:

      1. Deploy SNO via ZTP with workload partitioning enabled
      2. Check mgmt pods affinity
      3.
      

      Actual results:

      pods do not have workload partitioning annotation, and are not pinned to mgmt cores

      Expected results:

      All management pods should be pinned to reserved cores
      
      Pod should be annotated with: target.workload.openshift.io/management: '{"effect":"PreferredDuringScheduling"}'
