> Currently our getAll returns a map of entries that exist in the cache in any order.  We could enhance this to return a map where the entries are in the same iteration order of the Set (important when the user uses a LinkedHashSet).  We could even do something like List<V> getAll(List<K>) to show better ordering as an option too.
> This has 2 immediate advantages.
> 1. Remote getAll no longer requires to serialize all the keys in the response since it knows which values map to which keys based on what it sent.
> 2. Query results need ordered List as well. See query/src/main/java/org/infinispan/query/impl/EntityLoader.java
