Changes Unknown when pulling f319ddf on runtime-caching-plugins-update into ** on v3**.

[jeffposnick]

This PR takes the current functionality in v3 and pretty directly migrates it to support the new Plugin-based approach to configuring everything.

I also filed #1096 to track a larger discussion about runtimeCaching.options in v3, and that might lead to follow-up PRs depending on what the resolution is.
