### Changes: - Created `CacheableNetworkOperationFactory` to abstract operation and cache key creation - Instead of always creating an operation, we create a factory first, which pre-computes the cache key - This cache key is used to determine if it's a cache hit, as well as for the subsequently created operation I'm still investigating a leak (#2105), and I suspect it's coming from us creating and storing completion blocks, and those staying in memory beyond the lifetime of the operation. This refactor and performance improvement helps us avoid get more things in memory than we need to. See #2138 for how this is tested.
