From the user experience, as a customer, I'd like to be alerted if the action is a destructive operation:

• Add alert dialog when delete a machine pool
• Add alert flag in the 'change setting' dialog when do 'mark api private'.
• Add alert flag in the 'Delete cluster' dialog when delete a cluster.
• Add alert flag in the 'Uninstall add-on...' dialog when uninstalling an add-on from the cluster.

The hibernation dialog should be a good example.
