Description

As a follow-up to KIP-54, remove the dependency of Sticky Assignor to previously calculated assignment. This dependency is not required because each consumer participating in the rebalance now notifies the group leader of their assignment prior to rebalance. So the leader can compile the previous assignment of the whole group from this information.
