> It would be handly to have listener interface for components that should 
> react to PME instead of just adding more and more calls to 
> GridDhtPartitionsExchangeFuture.
> In general, there are four possible moments when a compnent can be notified: 
> on exchnage init (before and after topologies are updates and exchange latch 
> is acquired) and on exchange done (before and after readyTopVer is 
> incremented and user operations are unlocked).
