Seek in KafkaSpout

[Mitchell Rathbun (BLOOMBERG/ 731 LEX)]

Looking through the documentation, it seems that KafkaSpout does not expose any 
way to set the offset the spout reads from after the initial poll. This 
functionality is supported in KafkaConsumer through the seek() method. Am I 
correct that this isn't supported? Has anyone found a way to mimic the behavior 
of seek() with KafkaSpout?
