Cache.keySet(),entrySet(),values(),size() ignore contents of cache loader

Passivated cache entries are not represented in values returned by the keySet(), entrySet(), values(), and size() Cache methods. This results in inconsistent behavior, since it is possible that a given cache key may not be contained in keySet() even though Cache.get(...) would return a non-null value if the entry was previously passivated.

I think CacheLoaderInterceptor needs to implement the following methods:

Object visitSizeCommand(InvocationContext ctx, SizeCommand command) throws Throwable
Object visitValuesCommand(InvocationContext ctx, ValuesCommand command) throws Throwable
Object visitEntrySetCommand(InvocationContext ctx, EntrySetCommand command) throws Throwable
Object visitKeySetCommand(InvocationContext ctx, KeySetCommand command) throws Throwable
