    Adjust pxeboot config files path in an upgrade

    During the upgrade from stx6.0 to stx7.0, the content of
    /opt/platform/config/22.06/pxelinux.cfg/ is copied from the previous
    release. This way, the grub.cfg, which is a symlink, points to
    /pxeboot/pxelinux.cfg.files/grub.cfg. As in release stx7.0
    /pxeboot was moved to /var/pxeboot, the symlink should be recreated
    to point the correct path, which is
    /var/pxeboot/pxelinux.cfg.files/grub.cfg. This fix recriates the symlink
    pointing to the correct path.

    Note:
     cert-manager
     nginx-ingress-controller
     oidc-auth-apps
     platform-integ-apps

     The above apps were removed from upgrade path on 65-k8s-app-upgrade.sh
     script to finish upgrade process successfully

    Test plan
      PASS: Run initial bootstrap successfully
      PASS: Upgrade AIO-DX from stx6.0 to stx7.0
