go_kafka_client now exposes the OffsetStorage interface to be flexible about managing your offset.
go_kafka_client now also supports Kafka offset storage with Siesta library. To take advantage of this feature you should include the following to your ConsumerConfig:
config := DefaultConsumerConfig()
// your configurations go here
config.OffsetStorage = NewSiestaClient(config)
The default offset storage for now is still Zookeeper though and needs no additional configuration to get it working.
