Task: workarena.servicenow.sort-hardware-list
Goal: Sort the "hardware" list by the following fields:
 - Asset function (descending)
 - PO number (ascending)
 - Stockroom (ascending)
Task configuration: {'sort_dirs': ['desc', 'asc', 'asc'], 'sort_fields': ['asset_function', 'po_number', 'stockroom'], 'table_name': 'alm_hardware'}
