Print what this install is running, as JSON, and exit.

No network, no signing, no Final Target involvement. It exists so a master
install sharing the same server can read a tenant's details directly:

    /path/to/tenant/venv/bin/python manage.py ft_report --settings=config.settings.production

Used by ft_collect on the Final Target side.
