juju fails to bootstrap on default aks cluster size

[Richard Harding]

The az tool in edge snap is a version that seems to have changed the default size for a cluster node to a Standard_DS1_v2 vs a Standard_DS2_v2

This means that when I create the cluster I cannot bootstrap to it. It seems worth checking and failing early vs timing out waiting for pods to come up that fail in an unscheduled state.

    Fails:
    az aks create --resource-group aks --name forrester-cluster2 --node-count 3 --generate-ssh-keys

    Succeeds
    az aks create --resource-group aks --name forrester-cluster2 --node-count 3 -s Standard_DS2_v2 --generate-ssh-keys

Looping back to this: an underlying problem here is that the edge snap has an outdated version of the az tool.

Newer versions of the tool default to Standard_DS2_v2.

I think that the fix for this is to update the docs -- instructing operators to make sure that they have an newer version of the tool, and to check their default instance type if they don't.

I'd argue that there could be some logic in bootstrap to help detect a
failure to have enough resources and fail early/clearly as well. The docs
is a great first step for sure.
