Azure-cli: az aks prints incorrect error if resource group doesn't exist.

[benofben]

If you try to create an AKS cluster and the target resource group doesn't exist, the error message isn't very clear on what the issue is:

Bens-MacBook:~ ben$ 
Bens-MacBook:~ ben$ 
Bens-MacBook:~ ben$ az aks create --resource-group myResourceGroup --name myAKSCluster
Finished service principal creation[##################################]  100.0000%Operation failed with status: 'Bad Request'. Details: Changing property 'servicePrincipalProfile.clientId' is not allowed.

Looks like the same thing happens on Power Shell as well.

@benofben I can't reproduce the error.

$ az aks create --resource-group bogus --name myAKSClsuter
Resource group 'bogus' could not be found.

I am getting the same error. Deleting aksServicePrincipal.json and trying again did not help.

Operation failed with status: 'Bad Request'. Details: Changing property 'servicePrincipalProfile.clientId' is not allowed.

[mboersma]

Since the check for the existence of the resource group is the first thing the CLI does here, I think the errors reported are mistaken. It's more likely the RG and Cluster do exist--this is the error you would get when trying to create a new cluster over an existing one.

[mboersma]

We've never been able to reproduce this. The error message is immediate and clear:

$ az aks create -g bogus -n MyCluster
Resource group 'bogus' could not be found.

This was reported while AKS was still in preview, so it's possible there was a CLI bug that's been fixed since then, although I cant' find one specific to this. @tjprescott let's close this issue.
