[BZ 959455] - Confusing number of total rows in Administration->Agents page - calling setPagingInfo(response, result); solves the issue. I fixed that also for StorageNodeDatasource, AffinityGroupWithCountsDatasource, FailoverListItemDatasource, PartitionEventDatasource, ServerDatasource and ServerWithAgentCountDatasource
