This change is a follow up on the effort to remove transactions and sync stores from the database layer, and move them in the application layer. It is addressing the repo + space store. The following changes are included: - Introduce PathStore storing resource paths (repo + space) - Add foreign key from path.repo_id/space_id to repo.id/space.id - Add foreign key from repo/space.parent_id to space.id - Remove repo_sync and space_sync - Move path creation logic to repo/space controller (for both creating primary paths for new repos/spaces, as well as creating alias spaces) - Reimplement repo/space moving on controller layer
