Deprecated default functions in DefaultedRedisConnection

[mjimani]

DefaultedRedisConnection class was deprecated. It is recommended to replace functions using the RedisKeyCommands class.

We're using the deprecated default method arrangement for quite a while now. We eventually want to remove all deprecated forwarding as it adds to our complexity of use. However, such a refactoring would potentially cause a lot of effort in the calling code. Therefore, we're looking forward to another event that would be a good justification for a larger change, such as consolidation of Java Redis Clients so that we could potentially remove one of the two clients in favor of a much simpler arrangement.
