class RouteGroupCacheContext in Group 8

Defines a cache context for "per group from route" caching.

Please note: This cache context uses the group from the current route as the context value to work with. This context is therefore only to be used with data that was based on the group from the route. A good example being the 'entity:group' context provided by the 'group.group_route_context' service.

Cache context ID: 'route.group'.
