feat: add data import/export commands

[yann-soubeyrand]

This simplifies the provisioning of local development environments. One can setup its organization, project, users, etc, and export instance data to a JSON file. Then, when creating a new development environment, the JSON file can be imported to the newly created instance.

Hi @yann-soubeyrand, do you intend to continue work on this PR?

[yann-soubeyrand]

Hi @muhlemmer, sorry for the late reply. Yes, I’d be glad to work on this again, but I’ve just no time for it for the moment. My first intention when I opened this PR was to share the code which I used in a project.
