Introduces Group import feature with ndjson

Merged Kassio Borges requested to merge group-import-with-ndjson into master

#212327 (closed)

What does this MR do?

To improve performance, and the memory footprint of the group import feature, the ability to import a group-tree in the ndjson format is being introduced. This feature is behind a feature flag (:group_import_export_ndjson) for now.

Originally all the effort to enable ndjson on for Group Import/Export feature was done in one MR, which endup being too big. @ayufan then suggested to split that work on smaller MRs to make the work easier to review.


Does this MR meet the acceptance criteria?
