CacheKeyComputer: Include split rules in computation
Chunk artifacts need the [(artifact_name, [regular_expression])] so that if the default split rules change, or the blending rule changes, then an extra version field doesn't need to be added to the cache key computer. This is for future plans to allow the split rules to be configurable and allow us to more easily change them. System and Stratum artifact computations don't need this, since those splitting rules are already expressed in the dependencies information.
