Description of problem:

When creating an image for Azure via the CLI, the architecture (arch) and operating system (OS) are mandatory parameters. However, this requirement is not mentioned in the documentation. 

For other cloud services, the documentation clearly specifies these mandatory parameters, but this information is missing only for Azure. As a result, when users follow the Azure documentation as it currently stands, the CLI always prompts for the arch and OS parameters, as shown below.

hammer compute-resource image create --name RHEL9 --compute-resource AZURE-SAP --uuid 'gallery://RHSG_1/RHEL77img' --username azureusername --password xxxxxxxx --user-data yes
Could not create the image:
  Operatingsystem can't be blank
  Architecture can't be blank

Actual behavior:
The documentation is currently missing the architecture and OS details for Azure.

Expected behavior:
The arch and os parameters should be present, as they are required parameters for Azure.
