Description of problem: When Importing a cluster by using auto-import and pushing clusterInstance yaml, ACM launches the provisioning of the cluster by setting BMH status to provisioning and start the inspection with the iso

Version-Release number of selected component (if applicable): ACM 2.15

How reproducible: always

Steps to Reproduce:

1.  follow this procedure https://docs.google.com/document/d/1oKCk69Nnux-adc8sjmGe5tbEk5TZEHOUpZH17cXIvXU/edit?tab=t.0#heading=h.mc0urzjrdwgx
2.  
3. ...

Actual results: ACM imports the cluster but it start the inspection of the nodes 

$ oc get cluster instance

 oc get clusterinstance -n lzhocp
NAMESPACE     NAME          PAUSED   PROVISIONSTATUS   PROVISIONDETAILS                                                             AGE
lzhocp        lzhocp                 Completed         Cluster is installed (detected from ClusterDeployment Spec.Installed=true)   22m

$ oc get bmh -n lzhocp
NAME                                            STATE          CONSUMER   ONLINE   ERROR   AGE
master-0.lzhocp.se-lab.eng.rdu2.dc.redhat.com   provisioning              true             23m
master-1.lzhocp.se-lab.eng.rdu2.dc.redhat.com   provisioning              true             23m
master-2.lzhocp.se-lab.eng.rdu2.dc.redhat.com   provisioning              true             23m

The bmh are showing provisiong and iso is mouinted and the nodes are being rebooted

Expected results: The cluster import process must not launch the provisioning of the nodes
