interface RenderCacheBackendAdapterInterface in Render cache 7.2

Defines an interface for the render cache backend adapter.

This is an adapter from the render cache, caching implementation to the Drupal 7 cache interface.

This implements advanced Drupal 8 features like cache tags using a cache re-validation strategy.

An implementation supporting cache tags natively can switch out the service.
