Description of problem:

Disconnected IPI OCP 4.10.22 cluster install on baremetal fails when hostname of master nodes does not include "master"    

Version-Release number of selected component (if applicable): 4.10.22

How reproducible:  Perform disconnected IPI install of OCP 4.10.22 on bare metal with master nodes that do not contain the text "master"

Steps to Reproduce:

Perform disconnected IPI install of OCP 4.10.22 on bare metal with master nodes that do not contain the text "master"

Actual results: master nodes do come up.

Expected results: master nodes should come up despite that the text "master" is not in their hostname.

The code for the cluster-baremetal-operator at the following link: 

https://github.com/openshift/cluster-baremetal-operator/blob/49d7b249c5dcef8228f206eff4530a25f03b201f/controllers/provisioning_controller.go#L441

The following condition is concerning:

if strings.Contains(bmh.Name, "master") && len(bmh.Spec.BootMACAddress) > 0

The packages reveal that bmh.Name references the name inside the metadata of the BMH object. 

Should a customer have masters with names that do not include the text "master", the above condition can never become true, and so, the following slice is never created :

macs = append(macs, bmh.Spec.BootMACAddress)
