User Story

As a user I want to see what differs between the Machine's (current) ProviderSpec and the Control Plane Machine Set (desired) ProviderSpec so that I can understand why the CPMSO is replacing my control plane machine.

Background

Work spawn out of discussions in https://redhat-internal.slack.com/archives/CCX9DB894/p1678820665803259 and https://redhat-internal.slack.com/archives/C04UB95G802 

Believe we are already logging this, would be good to emit either an event or the diff into the status, whoever takes this card should investigate the best way of surfacing this.

Outcome:

• Decision on event/status/both
• If status, API design scoped out
• Cards written for implementation

Steps

• PR
• update tests

Stakeholders

• <Who is interested in this/where did they request this>

Definition of Done

• <Add items that need to be completed for this card>

• Docs

• <Add docs requirements for this card>

• Testing

• <Explain testing that will be added>
