Chassis: Add UUID property

This commit adds the support for implementing the "UUID" property
as defined in the Redfish Chassis schema.

UUID will enable further platform/board specific monitoring and control.

Redfish validator passed.

  "Id": "GPU1",
  "Name": "GPU1",
  "UUID": "7b6e8e55-f0d5-4a9f-84a3-61635a3bc232"
