[azure-cli] New scale out settings for consumption and premium

Glenna and Wenonah have completed work recently so that:

1. Consumption apps can specifiy a max scale out and an app will stop scaling at that number
2. Premium apps can specify a minimum instance that will always be running

We want to make sure both are surfaced in the AZ CLI. Glenna and Wenonah have details on the ARM properties. They went live in 88 and 87.1 respectively

No files or tests are named. Start by locating the Azure CLI handling for consumption and premium app settings, then confirm the ARM property details for maximum scale-out and minimum instances with Glenna or Wenonah. Done means both settings are surfaced in the CLI for their respective app types.
