[Hubs] Support Alibaba cloud FOCUS data

[Copilot]

This PR adds support for Alibaba Cloud FOCUS data ingestion in FinOps hubs by implementing the required custom columns as specified in the Alibaba Cloud Standard Billing FOCUS documentation.

Changes Made

Added Alibaba Cloud FOCUS Columns

The following extended columns have been added to support Alibaba Cloud cost data:

• x_CommodityCode - Commodity code identifier
• x_CommodityName - Commodity name description
• x_BillingItemCode - Billing item code identifier
• x_BillingItemName - Billing item name description
• x_InstanceID - Instance identifier

Files Modified

1. src/templates/finops-hub/modules/scripts/IngestionSetup_RawTables.kql

   • Added Alibaba 1.0 reference to supported versions documentation
   • Added 5 new columns to Costs_raw table definition with appropriate data types
   • Added corresponding ingestion mappings for all 5 columns

2. src/templates/finops-hub/modules/scripts/IngestionSetup_v1_0.kql

   • Added 5 new columns to ActualCosts_transform_v1_0() function with empty default values
   • Added 5 new columns to AmortizedCosts_transform_v1_0() function with empty default values

3. docs-mslearn/toolkit/hubs/data-model.md

   • Updated documentation to include Alibaba Cloud in the list of supported cloud providers

4. docs-mslearn/toolkit/hubs/data-processing.md

   • Added Alibaba Cloud FOCUS 1.0 to the list of supported but not natively integrated datasets

Implementation Notes

• This implementation follows the exact same pattern used for Tencent cloud support (PR [Hubs] Support Tencent FOCUS data #1274)
• All columns use the x_ prefix to denote them as extended FOCUS columns
• Default values are set to empty strings to maintain compatibility with existing data
• Changes are minimal and focused only on the required functionality
• No breaking changes to existing functionality

Testing

• Verified KQL syntax is correct across all modified files
• Confirmed all 5 columns are properly defined in table schema
• Validated all 5 columns have corresponding ingestion mappings
• Ensured all 5 columns are included in both transform functions
• Documentation updates reflect the new capability

This enables Alibaba Cloud users to ingest their FOCUS cost data into FinOps hubs with full support for Alibaba-specific billing metadata.

Fixes #1677.
