[Telemetry] Language of cells on run

[claudiaregio]

VS Code Specific: I'd like to be able to see the language of cells in the notebook in their sequence on run. (Assuming I can get the last run based on cell ID)

For example, if someone has a notebook with the first cell as a SQL cell and the next 3 cells as C# cells, I'd like to see something like this stored in the telemetry when the notebook is saved: [SQL, C#, C#, C#]

My proposal would be to capture the following information on each cell run:

• A cell ID
• A document ID
• The execution order
• The cell language
• Whether it executed successfully
• Execution time

If document ID is bound to the file name or something that is persistent when I close the document and then reopen it I would suggest we also capture a session ID that is tracking the lifespan of an open document.

Also ............ how about we are able to track source and destination languages for each use of #!share? that would draw a picture about the intentional interaction between languages.
