Question about managing dependencies between extensions on scaleset

Hi Azure

This is regarding
https://github.com/Azure/azure-quickstart-templates/tree/master/201-dependency-between-scripts-using-extensions

Do we have an example for doing the same thing on scale sets? In particular, the `dependsOn` field is not very clear.

On the vm level, I would do this

```
"dependsOn": [
"[concat('Microsoft.Compute/virtualMachines/', variables('myVMName'), '/extensions/MyExt')]"
],
```

Since I don't have a VM name on a scaleset configuration, what would I do?

Start with the linked 201-dependency-between-scripts-using-extensions template and inspect how its dependsOn field expresses extension ordering. Compare that example with the scale set configuration and Azure's scale set extension dependency guidance; the work is done when a scale set example clearly documents the correct dependency expression.
