Enable the Power BI Connector for Microsoft CQD for Government Tenants

Currently the CQD (Call Quality Dashboard) Power BI connector only works when using Power BI Desktop but is not compatible with the Power BI service for GCC (per https://docs.microsoft.com/en-us/microsoftteams/cqd-power-bi-connector#limitations). Not having the ability to host, publish, and share these dashboards through the Power BI service has made it harder to onboard and administer Teams as a phone system within our organization and reduced the overall value we can receive from Teams as a phone system.
