Failed to put OVSDB bridge and termination points into CONFIG data store

SfcSffToOvsMappingAPI -> INFO -> Cannot build OvsdbBridgeAugmentation. Missing OVS Node augmentation on SFF SFF1.

This happens when Service-Function-Forwarder is put into config DS ( http://pastebin.com/Fs8JAXuc)

onDataChange method is triggered in SfcOvsSffEntryDataListener in which OvsdbBridgeAugmentation gets resolved. This process involves reading from network topology in OPERATIONAL datastore (http://controllerIp:port/restconf/operational/network-topology:network-topology/topology/ovsdb:1). The problem is, that those data are not rendered from OVS right away. It takes a while to have them present. So if anyone tries to write Service-Function-Forwarder data to OPERATIONAL sooner, Node augmentation can not be read.
