    2. Delete and re-create a test workload multiple times and check the phc2sys process openshift_ptp_clock_state between iterations

Actual results:

    openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="api.kni-qe-74.lab.eng.rdu2.redhat.com",process="phc2sys"} 0

Expected results:

    openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="api.kni-qe-74.lab.eng.rdu2.redhat.com",process="phc2sys"} 1
