Create support for the long-running operations for the “calculate” (Excel) API in Microsoft Graph

Some Graph operations take an indeterminate amount time to complete. It is easy to hit timeout while waiting for the response to these requests. To resolve this issue, Microsoft provides the long-running operation pattern. When you use this pattern, you don't need to worry about the timeout for the request. Unfortunately, the long running operation pattern doesn’t yet support all Excel-related operations. Specifically, the Calculate operation isn’t yet supported. Recalculating a large and/or complex Excel workbook frequently times out, making subsequent operations (save as PDF, reading values from cells, etc.) unreliable or impossible.
