feat: add Azure Managed Identities attributes for ARO-HCP Clusters

[miguelsorianod]

We add Azure Managed Identities related attributes that are going to be leveraged for the ARO-HCP Clusters.

@machi1990 I think it should be fine to add this even when we don't have any code in CS to map in/out.

My understanding is that if the new content of the OCM SDK Go is leveraged:

• When creating the type using the OCM SDK Go and it is sent to CS then CS will deserialize into the CS specific API type and nothing else will happen as there are no validations nor mapping to model layer.
• When reading from CS and serializing into the OCM SDK Go type the attributes won't exist from CS so the corresponding attributes in the OCM Go SDK type will not be set or set to zero-values

Would you agree?

Yes. That's what will happen. In my opinion, it should be safe to roll this one out once review.

I've added it to my list and I'll get to reviewing it at some point today.

Spotted one typo and left a corrective suggestion. Good to merge once addressed.
