[SPARK-20057][SS] Renamed KeyedState to GroupState in mapGroupsWithState
## What changes were proposed in this pull request?
Since the state is tied a "group" in the "mapGroupsWithState" operations,
its better to call the state "GroupState" instead of a key. This would make it
more general if you extends this operation to RelationGroupedDataset and python
APIs.
## How was this patch tested?
Existing unit tests.
