Remote jupyter server failures are not diagnosable

[rchiodo]

Was helping somebody today and their default kernel spec was invalid. There's no way to tell from the Jupyter extension.

We need at least the console output from the jupyter server. I had tried adding this to jupyter a long time ago and they were hesitant.

Maybe we could tell the user to look at the console output instead.

This seems like it could be a frequent problem. Look to see if telemetry can validate. Perhaps there's something we can do to grab the output from the jupyter console.

Closing this issue as there's nothing to be done here,
