DFS Connection Schedule

When replication is set to be available in the schedule, replication MUST occur continuously. Unlike SYSVOL schedules, DFS replica set schedules are on/off schedules. As long as the schedule is open, the connection stays in the Joined state and change orders MUST be sent out as they are processed by the Upstream Partner. Any queued change orders in the upstream partner's outbound log MUST be sent first. When the schedule closes, FRS unjoins the connection.
