Moved routing/bgp config into common routing bundle.

This allows the configuration to be used from multiple applications.

 * The class that reads the configuration file is now a service so that
   config can be consumed by components in other bundles.
 * Name of config reader classes has been generalized to RoutingConfigService
 * All config has been added to RoutingConfigService, instead of having
   two service interfaces like we did previously
