ConfigStore.Base is not set; cannot determine Azure storage

Error message

ConfigStore.Base is not set; cannot determine Azure storage account

What it means

Empty-input guard in azureStorageAccountFromConfigStore: the cluster's ConfigStore.Base (state location) is empty, so the Azure storage account for the state store cannot be derived. Fires when the cluster spec lacks a config base on Azure clusters.
