feat(startup): update logic for metadb update on startup, skip unmodified repos (#2024)

- MetaDB stores the time of the last update of a repo
- During startup we check if the layout has been updated after the last recorded change in the db
- If this is the case, the repo is parsed and updated in the DB otherwise it's skipped
