Deleting provisioned bmh when trying to replace master node get stuck during deprovisioning

4.12.0-rc.2

One time so far but this has been reported in BZ#2077059 

1. Follow steps replacing unhealthy etcd memeber

https://docs.openshift.com/container-platform/4.11/backup_and_restore/control_plane_backup_and_restore/replacing-unhealthy-etcd-member.html#restore-replace-stopped-etcd-member_replacing-unhealthy-etcd-member

Steps 1 and 2

This was next step to replace bare metal control plane node

1. Follow https://docs.openshift.com/container-platform/4.11/installing/installing_bare_metal_ipi/ipi-install-expanding-the-cluster.html#replacing-a-bare-metal-control-plane-node_ipi-install-expanding
2. Step 2: Remove the old BareMetalHost and Machine objects: 
oc delete bmh -n openshift-machine-api master-2.kni-qe-31.lab.eng.rdu2.redhat.com
baremetalhost.metal3.io "master-2.kni-qe-31.lab.eng.rdu2.redhat.com" deleted

^^ get hung 

There were two known bugs reported that have still not resolve it.
https://bugzilla.redhat.com/show_bug.cgi?id=2077059
https://bugzilla.redhat.com/show_bug.cgi?id=2087213

The work around is to delete the finalizer.  It seems been a very common issue and we should address it
especially seen in our Nokia System Test BM  [kni@registry.kni-qe-31 MASTER_NODE_REPLACEMENT]$ oc get clusterversion
NAME      VERSION       AVAILABLE   PROGRESSING   SINCE   STATUS
version   4.12.0-rc.2   True        False         2d4h    Error while reconciling 4.12.0-rc.2: the cluster operator etcd is degrade
oc delete bmh -n openshift-machine-api master-2.kni-qe-31.lab.eng.rdu2.redhat.com
baremetalhost.metal3.io "master-2.kni-qe-31.lab.eng.rdu2.redhat.com" deleted** Gets stuck ^^
oc edit bmh -n openshift-machine-api master-2.kni-qe-31.lab.eng.rdu2.redhat.com
REMOVE finalizer "baremetalhost.metal3.io"# we can now see it removed
oc get bmh -n openshift-machine-api
NAME                                         STATE       CONSUMER                   ONLINE   ERROR   AGE

master-1.kni-qe-31.lab.eng.rdu2.redhat.com   unmanaged   kni-qe-31-dsbn7-master-1   true             2d5h

I am not sure which logs you want but there was mention from this image-customization in previous bugs. Please let me know 
what logs you need?

get hung and won't delete bmh

delete bmh per user document

I was deleting again today (12/8/22) and it appears to the user stuck again.  I was looking at some ironic command and it showed Provisioning State = clean failed.
