AKS Kontainer Engine v2 will use cloud credentials. For checking AKS
cluster capabilities cloud credentials should be also used.
AKS Kontainer Engine v1 should works as before.

Example test HTTP call for testing cloud credentials

    ```
    $ curl -u $TOKEN "https://localhost:8443/meta/aksVersions?cloudCredentialId=cattle-global-data:cc-abcde&tenantId=3572c671-f13a-4d01-aa5e-b100b54111fa&region=eastus
    ```
