Subject: [PATCH] Provide an MDSalNodeFactory to construct an MD-SAL node for
 NB interfaces like the Forwarding Rules Manager

When you try to get flows using the FR NB API for a given node you have to provide both a node type and node id. Since MD_SAL nodes
have a type MD_SAL which is not one of the standard types you need to provide and register a NodeFactory which can construct a Node
for an MD_SAL Node type.
