> The partition.assignment.strategy config is deprecated with the new consumer group protocol KIP-848. With the new protocol, server side assignors are supported for now, defined in the property
> group.remote.assignor, and with default values selected by the broker, so it's not even a required property. 
> The new AsyncKafkaConsumer supports the new protocol only, but it currently throws an IllegalStateException if a call to subscribe is made and the deprecated config partition.assignment.strategy is empty (see [throwIfNoAssignorsConfigured|https://github.com/apache/kafka/blob/056d232f4e28bf8e67e00f8ed2c103fdb0f3b78e/clients/src/main/java/org/apache/kafka/clients/consumer/internals/AsyncKafkaConsumer.java#L1715]).
>  
> We should remove the reference to ConsumerPartitionAssignor in the AsyncKafkaConsumer, along with it's validation for non-empty on subscribe (only use it has)
