*  Added ActionCable::SubscriptionAdapter::EventedRedis.em_redis_connector/redis_connector and
   ActionCable::SubscriptionAdapter::Redis.redis_connector factory methods for redis connections, 
   so you can overwrite with your own initializers. This is used when you want to use different-than-standard Redis adapters,
   like for Makara distributed Redis.

*   Create notion of an `ActionCable::SubscriptionAdapter`.
    Separate out Redis functionality into
    `ActionCable::SubscriptionAdapter::Redis`, and add a
    PostgreSQL adapter as well. Configuration file for
    ActionCable was changed from`config/redis/cable.yml` to
    `config/cable.yml`.
