Add collection cache versioning
Cache versioning enables the same cache key to be reused when the object being cached changes by moving the volatile part of the cache key out of the cache key and into a version that is embedded in the cache entry. This is already occurring when the object being cached is an `ActiveRecord::Base`, but when caching an `ActiveRecord::Relation` we are currently still putting the volatile information (max updated at and count) as part of the cache key. This PR moves the volatile part of the relations `cache_key` into the `cache_version` to support recycling cache keys for `ActiveRecord::Relation`s.
