Backend LRU cache doesn't support stream isolation #112

All queries to a Backend use the same LRU cache, which will leak state between queries. This is harmful for use cases such as Tor, where stream-isolated connections should not share any state. We should fix this by implementing stream-isolated LRU caches.
