Bug 5061: Move BGP topology providers configuration to config DS
Allow to configure BGP topology provider from config DS Topology subtree.
The BGP topology provider configuration consists of topology-id,
rib-id (where topology provider is listening) and topology-type (identifies the type
of the BGP topology provider - IPv4/6 reachability, linkstate).
Services are wired with Blueprint, while CSS module based configuration
is still preserved.
