fib: Decouple source from priority and behaviour
Type: feature the fib_source_t enum alone no longer defines the priority and behaviour, instead each source must be allocated these attributes. This allows the creation of other sources by the plugins (and soon over the API). Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I890ee820fbc16079ee417ea1fbc163192806e853
