Feature Overview

As a cluster admin for standalone OpenShift, I want to customize the prefix of the machine names created by CPMS due to company policies related to nomenclature. Implement the Control Plane Machine Set (CPMS) feature in OpenShift to support machine names where user can set custom names prefixes. Note the prefix will always be suffixed by "<5-chars>-<index>" as this is part of the CPMS internal design.

Acceptance Criteria

A new field called machineNamePrefix has been added to CPMS CR.
This field would allow the customer to specify a custom prefix for the machine names.
The machine names would then be generated using the format: <machineNamePrefix><5-chars><index>
Where:
<machineNamePrefix> is the custom prefix provided by the customer
<5-chars> is a random 5 character string (this is required and cannot be changed)
<index> represents the index of the machine (0, 1, 2, etc.)
Ensure that if the machineNamePrefix is changed, the operator reconciles and succeeds in rolling out the changes.
