CHANNELZ API *************/ churn as the feature is implemented. This comment will be removed once channelz is officially supported, and these APIs become stable. For now you may track the progress by following this github issue: https://github.com/grpc/grpc/issues/15340

the following APIs return allocated JSON strings that match the response objects from the channelz proto, found here: https://github.com/grpc/grpc/blob/master/src/proto/grpc/channelz/channelz.proto.
