Redis - Add a short description

I'm very technical and still can't explain message broker or streaming engine.

I think it needs to become less technical, and explain the benefit in simple terms:

Provides an integration with Redis, an open source, in-memory data store. This can speed up your Drupal site by serving cached items from memory rather than the database.

I like this latest version. Concise and non-technical. I often use language like this to explain caching to my clients.
