Abstract implementation of CacheDefinition
that caches
attributes for methods and implements a fallback policy: 1. specific target
method; 2. target class; 3. declaring method; 4. declaring class/interface.
Defaults to using the target class's caching attribute if none is associated with the target method. Any caching attribute associated with the target method completely overrides a class caching attribute. If none found on the target class, the interface that the invoked method has been called through (in case of a JDK proxy) will be checked.
This implementation caches attributes by method after they are first used. If it is ever desirable to allow dynamic changing of cacheable attributes (which is very unlikely), caching could be made configurable.

Logger available to subclasses.
As this base class is not marked Serializable, the logger will be recreated after serialization - provided that the concrete subclass is Serializable.
Determine the caching attribute for this method invocation.
Defaults to the class's caching attribute if no method attribute is found.
