Title: Don't hard depend on dalli

Other `ActiveSupport::Cache::Store` stores not powered by dalli still emit the same `ActiveSupport::Notifications`, like the one that comes with libmemcached. Removing this hard dependency is useful so we don't need to include the dalli gem to instrument a different store.
