Deploy to Azure errors for users

Need to ensure users can see why their deployment failed like PowerShell does

In general, there is error handling, however depending on the payload of the failure, we may not be parsing it properly since it depends on the back-end to return responses in a predictable way. If you can tell me the exact steps and template that you used to run into this problem, I can try and make sure we handle it properly.
