THIS IS BAD DESIGN. A. Indexer should directly subscribe to Knot event stream. Push-to-index is only for admin use and some edge cases. B. Index should be triggered just after the refUpdate event and not after the full git mirror resync is done. We are doing this because we don't have unified knotstream with basic repository state (ref list) passed as event payload. Should be updated later. Signed-off-by: Seongmin Lee <git@boltless.me>
