> With cayenne-jcache we lost the ability to invalidate caches not handled by Cayenne.
The API for CacheManager's caches introspection requires the caller to know the generic parameters
of a named cache. So we can no longer invalidate caches that were not created for Cayenne
(and that are known to be of type "Cache<String, List>"). 
> A few changes to address this:
> 1. Internally use "untyped" caches for storage. This would allow the same caches to be
reused by the code outside Cayenne.
> 2. Add API to QueryCache to handle invalidation of typed caches with known key and value
types. Extend @CacheGroups annotation to specify cache generics "signatures", add support
for it in CacheInvalidationFilter.
