1. Deploy spoke with GM and slave ptpconfigs
[kni@registry.kni-qe-61 ~]$ oc get ptpconfigs.ptp.openshift.io -A
NAMESPACE       NAME               AGE
openshift-ptp ...  du-ptp-slave-gm1   143m
openshift-ptp   du-ptp-slave-gm2   143m
openshift-ptp   grandmaster1       47h

    2. Check metrics (eno12399 and ens3f1np1 are slave)
# TYPE openshift_ptp_interface_role gauge
openshift_ptp_interface_role{iface="eno12399",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens3f1np1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens5f0",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f2",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens7f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2

    2. Delete slave ptpconfigs
[kni@registry.kni-qe-61 ~]$ oc get ptpconfigs.ptp.openshift.io -n openshift-ptp
NAME           AGE
grandmaster1   11h

     3. Check metrics 
[kni@registry.kni-qe-61 ~]$ oc exec -it ds/linuxptp-daemon  -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep role
# HELP openshift_ptp_interface_role 0 = PASSIVE, 1 = SLAVE, 2 = MASTER, 3 = FAULTY, 4 = UNKNOWN, 5 = LISTENING
# TYPE openshift_ptp_interface_role gauge
openshift_ptp_interface_role{iface="eno12399",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens3f1np1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens5f0",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f2",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens5f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2
openshift_ptp_interface_role{iface="ens7f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2    

[kni@registry.kni-qe-61 ~]$ oc exec -it ds/linuxptp-daemon  -n openshift-ptp -c linuxptp-daemon-container -- curl -s localhost:9091/metrics | grep role
# HELP openshift_ptp_interface_role 0 = PASSIVE, 1 = SLAVE, 2 = MASTER, 3 = FAULTY, 4 = UNKNOWN, 5 = LISTENING

openshift_ptp_interface_role{iface="ens3f1np1",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 1
openshift_ptp_interface_role{iface="ens5f0",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2

openshift_ptp_interface_role{iface="ens7f3",node="helix60.lab.eng.rdu2.redhat.com",process="ptp4l"} 2    

interfaces from deleted ptpconfigs should not appear in metrics
