Revert Flatcar Linux Azure to manual upload images

Browse Source 
* Initial support for Flatcar Linux on Azure used the Flatcar
Linux Azure Marketplace images (e.g. `flatcar-stable`) in
https://github.com/poseidon/typhoon/pull/664
* Flatcar Linux Azure Marketplace images have some unresolved
items https://github.com/poseidon/typhoon/issues/703
* Until the Marketplace items are resolved, revert to requiring
Flatcar Linux's images be manually uploaded (like GCP and
DigitalOcean)

### Flatcar Linux Images
Flatcar Linux publishes images for Azure. Azure allows custom images to be uploaded to a storage account bucket and imported.
[Download](https://www.flatcar-linux.org/releases/) a Flatcar Linux Azure VHD image and upload it to an Azure storage account container (i.e. bucket).
Azure requires fixed VHDs and Flatcar Linux provides dynamic VHDs, so uploads require Azure tools and cannot be done through the UI. Azure's tool compilation requires old versions, so Flatcar Linux has packaged a container image you may choose to use. See their [docs](https://docs.flatcar-linux.org/os/booting-on-azure/#uploading-your-own-image).
```
bzip2 -d flatcar_production_azure_image.vhd.bz2
```
```
podman run -it --entrypoint=/bin/bash quay.io/kinvolk/azure-flatcar-image-upload
...

# az storage account keys list --resource-group GROUP --account-name BUCKET | jq -r '.[0].value'

```
Create an Azure disk (note disk ID) and create an Azure image from it (note image ID).
```
az disk create --name flatcar-stable-2345.3.1 -g GROUP --source https://BUCKET.blob.core.windows.net/flatcar-linux/flatcar_production_azure_image.vhd
az image create --name flatcar-stable-2345.3.1 -g GROUP --os-type=linux --source /subscriptions/some/path/providers/Microsoft.Compute/disks/flatcar-stable-2345.3.1
```
Set the [os_image](#variables) in the next step.
