Description

We have boolean ClusterState#active(ClusterState) static method. It would be better to have an instance method boolean active().
Also, we have ClusterState#lesserOf static method. It needs for internal purposes. So we must move this method in an internal package.
We introduced new compute requests for getting/change cluster state from the client node as internal classes of GridClusterStateProcessor. We should move them to separate public classes for maintainability purposes.
