Provide an option to store in a database without redis

[justinallenmarsh]

With the upcoming release of rails, everything redis based has been dropped in favor of using the database. It would be great to be able to provide an option here where the user can use this gem without having to integrate redis into the stack.

Hi @jmarsh24

It is possible to add a new store adapter to support a database by choice (sqlite, mysql, pg, .etc).
It can be done as a local implementation in your project or you could contribute to this gem and submit a PR, I'd be glad to review it.
