********************************************** WARNING **********************************************
This script uses the Azure CLI 1.0 and has been deprecated. Please install the Azure CLI 2.0
(https://docs.microsoft.com/cli/azure/install-azure-cli) and use these 3 easy commands:
az login
az account set --subscription <Subscription ID>
az ad sp create-for-rbac
By default, the last command creates a Service Principal with the 'Contributor' role scoped to the
current subscription. Pass the '--help' parameter for more info if you want to change the defaults.
