ForwarderRegistrarServer - NSMgr registration service

func StartForwarderRegistrarServer 

func StartForwarderRegistrarServer(ctx context.Context, model model.Model) (*ForwarderRegistrarServer, error)

StartForwarderRegistrarServer - registers and starts gRPC server which is listening for Network Service Forwarder Registrar requests.

func (*ForwarderRegistrarServer) RequestForwarderRegistration 

func (r *ForwarderRegistrarServer) RequestForwarderRegistration(ctx context.Context, req *forwarderregistrarapi.ForwarderRegistrationRequest) (*forwarderregistrarapi.ForwarderRegistrationReply, error)

RequestForwarderRegistration - request forwarder to be registered.
