celery: change ini template to use sqlite for results 'amqp://' might be good - also for results, but seems to need additional non-trivial setup. And according to https://docs.celeryproject.org/en/3.0/whatsnew-4.0.html#features-removed-for-lack-of-funding it is deprecated. Kallithea only uses Celery results when repos are created or forked and user browsers are reloading pages to poll for completion. amqp seems like unnecessary complexity for that use case. Sqlite does however seem like a minimal but fine solution for the Kallithea use case in most setups.
