Tell us about the problem

In order to understand our users better, we need to check what's happening with users who have started from NativeScript Playground and are currently using CLI. Currently we are not sure what are the most common problems for these users. In order to resolve this, add some additional tracking data (only for users who have accepted to be tracked).

Which platform(s) does your issue occur on?

Both

Please provide the following version numbers that your issue occurs with:

• CLI: any
• Cross-platform modules: Not applicable
• Runtime(s): Not applicable
• Plugin(s): Not applicable

When a project is exported/downloaded from Playground, it will have a "playground" data in its package.json. On each CLI command, executed for this project, we should check the package.json, store the data from "playground" key in CLI's user settings and remove the data from the package.json.
