> Current implementation of GridDhtAtomicUpdateFuture is less than optimal. First of all, It allocates lots of collections. 
> We could improve that in several ways:
> 1) Better encapsulate logic around DHT future/request/response, so that collections are not exposed through methods directly.
> 2) Implement specialized version for update with a single key (the most common case).
> Once done, we will be able to easily add single DHT request/response for more efficient IO.
