Support for shared consumer group in sarama

Description

Recently kafka introduced experimental support for Queue and shared consumer group https://cwiki.apache.org/confluence/display/KAFKA/KIP-932%3A+Queues+for+Kafka

Java client has already exposed an api for the same. Ref: https://kafka.apache.org/40/javadoc/org/apache/kafka/clients/consumer/KafkaShareConsumer.html

Any plans to add support for sharedConsumerGroup in sarama as well?
