Nowadays, cache will be used on almost everywhere of Gitea and it cannot be disabled, otherwise some features will become unaviable. Then I think we can just remove the option for cache enable. That means cache cannot be disabled. But of course, we can still use cache configuration to set how should Gitea use the cache.
