[exporter] interactive cli and notebooks

[nfx]

Exporter has low adoption so far and it's related to the difficulty working with it. it's target use is interactive one-off export of PVC and ST deployments, so admin persona most likely will launch it in interactive mode without any env vars configured upfront. let's cater for this persona to roll out export with minimal SA assistance.

I'm really not sure about interactivity by default...

[nfx]

@alexott why not interactivity by default? it's too difficult as it is now. breaking change - of course it is, but exporter is experimental, so we can do that.

I just thought about this PR again. I see two additional issues:

• Permissions aren't emitted for notebooks
• We need to export workspace directories as well, and permissions for them. Otherwise, when we import everything back (for example, into new workspace), then permissions for directories will be set to admin
