> DataStreamer failed with "too many remaps" message even if non-data node enter\leave
topology.
> PFA repro attached. 
> Seems, we should ignore topology changes when non-data node enter\leave the grid. 
> And also we need to sure that remapping doesn't occurs when there is no data nodes in
grid any more, as remapping make no sense and more suitable message should be logged.
