Ability to assign a customized control plane machine name by the CPMS CR

1. Proposed title of this feature request

Ability to assign a customized control plane machine name by the CPMS CR

      2. What is the nature and description of the request?

Customer requires to apply customized nomenclature for the nodes. 

For workers it is applied as per machineset name but for control plane, in case of having CPMS CR as active mode,  the control plane machine inherit the name of the cluster:

 

 $  oc get controlplanemachinesets.machine.openshift.io                                               
NAME      DESIRED   CURRENT   READY   UPDATED   UNAVAILABLE   STATE    AGE
cluster   3         3         3       3                       Active   83m

 $ oc get controlplanemachinesets.machine.openshift.io cluster -o json | jq .spec.selector.matchLabels
{
  "machine.openshift.io/cluster-api-cluster": "ci-ln-87m0grk-1d09d-wgstj",
  "machine.openshift.io/cluster-api-machine-role": "master",
  "machine.openshift.io/cluster-api-machine-type": "master"
}

 $ oc get machine | grep master
ci-ln-87m0grk-1d09d-wgstj-master-0               Running   Standard_D8s_v3   eastus   3      83m
ci-ln-87m0grk-1d09d-wgstj-master-1               Running   Standard_D8s_v3   eastus   2      83m
ci-ln-87m0grk-1d09d-wgstj-master-2               Running   Standard_D8s_v3   eastus   1      83m

 $ oc get nodes | grep master
ci-ln-87m0grk-1d09d-wgstj-master-0               Ready    control-plane,master   78m   v1.27.6+f67aeb3
ci-ln-87m0grk-1d09d-wgstj-master-1               Ready    control-plane,master   78m   v1.27.6+f67aeb3
ci-ln-87m0grk-1d09d-wgstj-master-2               Ready    control-plane,master   77m   v1.27.6+f67aeb3

 

    3. Why does the customer need this? (List the business requirements here)

   Due to the organization compliance needs, it’s required to give specific nomenclature to the nodes.

   Customer has a big fleet of clusters and is working on their strategy for OCP 4.14 new installations

    4. List any affected packages or components.
