* Makes ParserCache take the root of the key as a constructor argument * Introduces a ParserCacheFactory Next steps: - convert FlaggedRevs to using this. - cleanup This assumes that we wouldn't want to differentiate the parser cache settings per use-case, as it is now for default vs flaggedrevs caches. There are only two settings: $wgParserCacheType - name of the BagOStuff to use $wgParserCacheExpireTime - the expiration time. I think if we wanted to have different settings for different caches, we could add that as a next step. Bug: T263583 Change-Id: I188772da541a95c95a5ecece7c7dd748395506c2
