Summary: Instead of using KeyError to indicate that data isn't found, let's use an Option. The Option type better encode that data is missing without having to do a potentially error prone downcast, this may also enable us to set RUST_BACKTRACE=1 everywhere as we won't except errors to happen often anymore, previously, Mercurial will slow to a crawl due to the many KeyError being thrown around. I initially wanted to keep the change small to help reviews, but that didn't really work out, as the dependencies on the `DataStore`/`HistoryStore` traits are all over the place...
