Add Microsoft Graph API as a connected service

[jourdant]

The Microsoft Graph API (http://graph.microsoft.io) is a unified ODATA endpoint to access data across Microsoft services. More specifically AAD/O365. There is a major reporting/auditing component of this service as well as other resources being useful to use in Power BI reports.

This is really needed. Hard to believe it was not switched off intentionally.

Please we need licenses and sku counts and we have to make external calls and save the data to OneDrive using PS or AZ SQL and it's just inefficient to save it. I don't know why this was removed.

Yes, this would be very, very helpful!
