Import-AzAksCredential is missing the Public-FQDN functionality

[fschmied]

Description of the new feature

With a private cluster, AKS will create two DNS entries: a private one and a public one. Import-AzAksCredential imports a kubeconfig with the private DNS name.

Sometimes, you need the public DNS name, e.g., when the machine you're connecting from can't resolve the private one. Azure CLI's az aks get-credentials therefore has a --public-fqdn option.

Import-AzAksCredential is missing that option and should get it, too.

Proposed implementation details (optional)

Should work the same way as az aks get-credentials --public-fqdn.
