> This is a follow-up on ISPN-11116. It's wrong for invalidation commands to load the previous value from the store, but we also have the opposite problem: in a distributed cache, when a node loses some segments and the store is not segmented, we use an {{InvalidateCommand}} to remove stale entries, and it doesn't actually remove any entries from the store. 
> Instead of keeping {{InvalidateCommand}} as is and finding another solution for removing stale segments, we could change {{InvalidateCommand}} to also remove entries from private stores.
> Invalidation mode is very unlikely to be used with private stores, but we don't actually prohibit it, so it's better for invalidation mode as well if {{InvalidateCommand}} removed entries from the private stores and ignored the shared stores. The only problem remaining is to actually optimize {{CacheLoaderInterceptor}} so that it doesn't load the previous value unless there is a listener.
