------------------------------------
Summary: pollResigned can short circuit to unattached on receiving
all endquorum acks
Key: KAFKA-18377
URL: https://issues.apache.org/jira/browse/KAFKA-18377
Project: Kafka
Issue Type: Improvement
Reporter: Alyssa Huang
Resigned state keeps track of `unackedVoters` and on pollResigned only sends
endQuorum requests to those voters. Right now it is not used to short circuit
the transition to Unattached once the set is empty.
It would be useful to short circuit this to allow the replica to discover any
new leader more quickly (say in the case that the node was removed from quorum,
the new leader would not be sending beginquorum requests to this node).
