- Upate vscode-nls to 4.0.0 in notebook extension. Should be fix for Insiders build failure due to localization package failing
- Updated samples to remove as vscode-nls if not needed, or update if still needed
- Updated samples using `npm audit fix`
- Fixed compile errors in all the samples
- Fixes#4129 Overlapping command help windows in notebook
- Do not show parameter hints for inactive cells, to avoid them hanging around when no longer selected
- Fixes#4116 Notebooks: Intellisense Doesn't Work using Add New Connection
- Move connect/disconnect logic to 1 place (code component) instead of 2
- Handle the case where you connect after choosing active cell. We now hook to the event and update connection
- Fix issues in sql session manager where result outputs 0 rows. This was failing to show the empty resultset contents, which is a regression vs. query editor. It also put unhandled error on the debug console
- Fix#3913 Notebook: words selected in other cells should be unselected on cell change
Note: after fix, now looks as follows. Need to do follow up to get correct grid min height

- Jupyter completion item support was awaiting info before responding. Fix is to check if this is even a notebook cell first, then only await stuff if that's true

* Move to using notebook language by default, with override in cell
* Update cell language on kernel change
* Tweak language logic so that it prefers code mirror mode, then falls back since this was failing some notebooks
* Add new package.json contribution to define language magics. These result in cell language changing. Language is cleared out on removing the language magic
* Added support for executing Python, R and Java in the SQL Kernel to prove this out. It converts to the sp_execute_external_script format
TODO in future PR:
* Need to hook up completion item support for magics (issue #4078)

* Removed all unnecessary node module imports, reducing size from 5.4MB to 86KB. We should probably do this for all extensions
