    Add instrumentation for kube_upgrade_control_plane

    This adds instrumentation for sysinv kube_upgrade_control_plane
    so that we see progress and more error reasons when retrieving
    kubernetes control-plane versions. This adds a few more places
    to generate exceptions so that a retry is performed.

    This enforces we must be able to get the versions from each
    control-plane component (kube-apiservver, kube-controller-manager,
    kube-scheduler) by querying pods that match expected pod name and
    container image.

    TEST CASES:
    PASS: Run orchestrated kubernetes upgrade: AIO-SX, AIO-DX, STANDARD.
          Verify we see new logs during upgrade control plane.
    PASS: Manually modify code to test likely exception paths causes retry.
