Moving this to 5.2 as now we have support for these methods in CacheLoader (load, loadAll, loadAllKeys) and it's important for the DistributedExecutors (ISPN-2279) to be able to also load entries from the database the same way MapReduceTask can.

> 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
