    KAFKA-3775: Intorduce new streams configuration max.tasks.assigned
    
    This configuration limits the maximum number of tasks assigned to a single KafkaStreams
instance.
    As a task consists of single partition for more than 1 topic, setting this value to lower
is useful
    to prevent huge number of partitions are assigned to an instance which started first.
