Pull request overview
This PR migrates the az vmss command group core commands (create, show, update, wait) from SDK-based implementation to AAZ-based implementation, following Azure CLI's ongoing effort to standardize on AAZ for compute resources.
Changes:
- Migrated
vmss show,vmss update, andvmss waitcommand registrations from SDK-based to AAZ-based implementation - Updated
create_vmssfunction to use AAZ-basedget_vmss_by_aazinstead of SDK-basedget_vmss - Modified Guest Attestation Extension installation logic to work with AAZ dictionary responses (camelCase keys)

The VMSS object retrieved from get_vmss_by_aaz returns camelCase keys (e.g., 'virtualMachineProfile'), but AAZ Create/Update commands expect snake_case argument names. Before passing the vmss dictionary to VMSSCreate, you must convert it using the convert_show_result_to_snake_case function.
Compare this to the update_vmss function (lines 4587-4593) which correctly performs this conversion:
from .operations.vmss import convert_show_result_to_snake_case
vmss = vmss_convert_show_result_to_snake_case(vmss)Without this conversion, the AAZ command will fail to properly map the dictionary keys to its argument schema, potentially causing the operation to fail or produce incorrect results.

May I ask where the logic for this line is implemented?
