Foreman Cache Store

I think my preferences are sort of captured in this: off the shelf solutions in general and the more flexible solutions.

With that in mind, is there no generic Rails caching solution out there? Currently foreman_memcache implies it’s very Foreman specific, but Caching with Rails: An Overview — Ruby on Rails Guides tells me there are out of the box Memcache and Redis cache stores out there. It means the user has full flexibility in their caching solution and we can use an off the shelf solution.
