QA:Testcase CoreOS Azure

Description

Launch Fedora CoreOS in Microsoft Azure from the next image.

Setup

1. Create a Microsoft Azure account if you don't already have one.
2. Install the Azure CLI.
3. Install coreos-installer:

   sudo dnf install coreos-installer

How to test

1. Create an Ignition config. You can use the simplest example available which includes your SSH key.
2. Follow the documentation for downloading the Azure image, uploading it to your subscription, and launching a VM from it. Use the next stream instead of stable when downloading with coreos-installer.
3. SSH into the machine using ssh core@ipaddress (replace ipaddress with actual values).
4. Don't forget to terminate your instance after you're done with testing, so that you don't end up paying for an eternal-running machine. You may also want to delete the uploaded image.

Expected Results

1. The system launches in Azure according to the instructions.
2. You can connect through SSH.
3. The linked documentation is clear, all steps are understandable, and nothing important is missing from it.
