------------------------------------------------------------------
- No need to have two separate tasks for partition size. It is enough to have
Long size task and cast long to int (with a proper range check and exceprion,
if needed) in CacheProxy
- Because of above, no need for int-size methods on IgniteInternalCache
interface
- No need to send the task to all nodes in the cluster. Method should map
partition to nodes and send the task only to responsible nodes.

- We should reserve partition and only count size of partitions in OWNING
state.

> It makes sense to add size calculation per partition. Actually the following
> methods should be added to the {{IgniteCache}} API.
> {code}
> public int size(int partition, CachePeekMode... peekModes) throws
> CacheException;
> public int localSize(int partition, CachePeekMode... peekModes);
> {code}
