Cache diff highlight in discussions This commit handles note diffs caching, which considerably improves the performance on merge requests with lots of comments. Important to note that the caching approach taken here is different from `Gitlab::Diff::HighlightCache`. We do not reset the whole cache when a new push is sent or anything else. That's because discussions diffs are persisted and do not change. 2018-12-16 11:00:43 -05:00			`---`
