Should az capi management delete delete the cluster?

[mboersma]

When testing we were surprised to realize that az capi management delete just removes CAPZ componentry from a management cluster, leaving the cluster intact. This makes semantic sense if "management" is taken to be "the CAPZ stuff," but the management commands explicitly refer to the cluster, so they disagree.

Following the principle of least surprise, we should consider changing this behavior to delete the cluster infrastructure instead. But if we did so, the command should check for the existence of managed clusters and offer the option of deleting those workload clusters first.

I believe it should delete the cluster and not just remove CAPZ components. Or if we keep this behavior be more explicit about it and update the help summary
