Encrypted Variables

[marcqualie]

Based on a discussion in the Ruby North east channel which originated from rails thread rails/rails#25095,

It seems encrypted variables could be a very useful feature for larger teams who don't want to cycle variables, but a more transparent approach than ejson would be preferred. This would also add security to production deployments where the configuration is shared.

Tying this into the global rails config/secrets.yml would simplify integration and share the same security as encrypted cookies.
