> GridCacheProcessor#restorePartitionStates method tries to employ striped pool
> to restore partition states in parallel but level of parallelization is down
> only to cache group per thread.
> It is not enough and not utilizes resources effectively in case of one cache
> group much bigger than the others.
> We need to parallel restore process down to individual partitions to get the
> most from the available resources and speed up node startup.
