The command `az aks upgrade` prompts for user input when you provide `--yes`

Describe the bug

Command Name az aks upgrade

Errors: The command is prompting for user input when --yes is provided.

Since control-plane-only argument is not specified, this will upgrade the control plane AND all nodepools to version 1.14.5. Continue? (y/N):

To Reproduce:

• az aks upgrade --resource-group {} --name {} --kubernetes-version {} --no-wait --yes

Expected Behavior

Provided the flag --yes I expect no user input needed to execute the command.

Since control-plane-only argument is not specified, this will upgrade the control plane AND all nodepools to version 1.14.5. Continue? (y/N):

Additional Context

[epierotto]

If the upgrade command by default prompts a confirmation message, why are you guys prompting a second confirmation message?

If further explanation needs to be provided to the user, to prevent unintentional operations, that could be done on the first prompt message. I see that you have this pattern of prompting twice in few commands there, but I would like to know the reason for doing so.

Also since that you have NoTTYException, that prevents some simple automation like: yes | az aks upgrade... or printf 'y\n' | az aks upgrade...

For a workaround @epierotto : az resource update --ids <aks_resource_id> --set 'properties.kubernetesVersion=<k8s_version>'--set 'properties.agentPoolProfiles[0].orchestratorVersion=<k8s_version>'
