[Feature] - Convert Existing Public AKS Clusters to Private

[nxf5025]

Is your feature request related to a problem? Please describe. According to https://learn.microsoft.com/en-us/azure/aks/private-clusters?tabs=azure-portal#limitations we are unable to covert existing AKS clusters from public to private:

There's no support for converting existing AKS clusters into private clusters.

Describe the solution you'd like Allow for users to migrate their public clusters to private.

Describe alternatives you've considered The alternative would be to terminate all our existing AKS clusters and rebuild as private. This will be a large burden on our organization which has hundreds of clusters.

I wrote a tutorial about this 3 days ago, maybe this helps you: https://blog.joeyc.dev/posts/aks-convert-public-to-private/

Will try to contact doc team in the future (or I should say when I want to) to see if this can be published as an official document. (Last time it costs me more than 1 year, not sure how long this time takes. This time it looks many relative documents needs to be double-confirmed to see if some statements should be changed, as this feature was identified as "not possible". If official did not admit/acknowledge this approach, then there is no official document anyway. So I really have little hope on this.)
