Description

Currently, we lookup the coordinator even if the user is using manual assignment and not storing offsets in Kafka. This seems unnecessary and can lead to surprising group authorization failures if the user does not have Describe access to the group. We should be able to change the code to only lookup the coordinator when we know we are going to use it.
