Settings for controlling if outputs should be saved to disk

[rebornix]

Maybe there is already an issue tracking this but I didn't find through search. It would be great if Jupyter has a setting to control if outputs should be transient or not. When set to true, Jupyter content provider can set outputs as transient so outputs change won't make the document dirty.

Thanks for the recommendation!

Have received significant amount of feedback from users who are using the native notebooks diffing experience.
They would like to able to omit outputs when git committing notebooks, specifically called out this example a few times.

I asked if using the "Clear all outputs" button in the global notebook toolbar would suffice for them but users mentioned not remembering that was up there and that they would like to be able to do it in one action not two. One user specifically called out the following extension:

I'm filing an issue in VS Code for discussion (moving this feature to VS Code) microsoft/vscode#124551

Can we not simply clear the cell outputs before saving the notebook? both commands are available, they just need to run in a sequence.
