class CacheContexts in Render cache 7.2

Defines the CacheContexts service.

Provides CacheContexts service using the render_cache container.

Note: The original Drupal 8 CacheContexts service uses the Symfony ContainerInterface, which is not available here. So we over- write the constructor to enable us to use the functionality of the stock file.
