Bug 6536: Allow propagation of SB notifications on slaves

First, add support for operational data store change notifications (we
only watched the config data store), since southbound originated
mappings are stored there.

Second, do not ignore southbound originated mappings coming from the
MD-SAL data store change notifications, if we're on a slave.
