control plane node count increments too early during provisioning

**What happened**:

Apparently out of sync messages in the logs during cluster creation. Let's take a 3-node control plane provisioning as an example.

During provisioning, the logs show messages like:

```
Scaling up control plane nodes, 3 expected (2 actual)","retries":367
```

But this is inaccurate in my opinion, because the `actual` counter increases the moment a node is being provisioned and not after it successfully comes up and acts as a control plane node :)

**What you expected to happen**:

The `actual` counter should only increment after a node is fully provisioned and functioning as a control plane node.

**How to reproduce it (as minimally and precisely as possible)**:

Create a cluster with a 3-node control plane and monitor the logs during provisioning. You will see the `actual` count incrementing early, even though the nodes aren't yet ready as control plane nodes.

**Anything else we need to know?**:

This can be misleading while watching provisioning progress or failures.

No file, test, or entry point is named in the issue. Start by locating the control-plane provisioning code that updates the actual node count, then reproduce a three-node control-plane creation and verify that the count changes only after nodes are fully provisioned and functioning.
