SQL Server 2014 SP1 image not available

[201-vm-sql-full-autopatching](https://github.com/Azure/azure-quickstart-templates/tree/master/201-vm-sql-full-autopatching)

### Issue Details

When deploying, getting this error:
```
Resource Microsoft.Compute/virtualMachines 'sql-server' failed with message '{
"error": {
"code": "ImageNotFound",
"target": "imageReference",
"message": "The platform image 'MicrosoftSQLServer:SQL2014SP1-WS2012R2:Enterprise:latest' is not available. Verify that all fields in the storage profile are correct."
}
}'

```

Open the linked 201-vm-sql-full-autopatching template and find the VM storage profile containing the SQL2014SP1-WS2012R2 imageReference. First reproduce the deployment error, then verify the image reference against available Azure images; done means the template deploys without ImageNotFound.
