We've had tons of issues related to people not having jupyter configured correctly (examples):
https://github.com/microsoft/vscode-python/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3A%22data+science%22+tornado
(as of this bug there were 18 issues just with tornado configuration).

We should ship our own jupyter to eliminate these issues. We can have the latest greatest all the time and use this to make sure we can install our own kernels.
