ZOOKEEPER-2959: ignore accepted epoch and ack from observers
https://issues.apache.org/jira/browse/ZOOKEEPER-2959
After a round of elections completes, followers and observers send their
accepted epochs to the leader to determine a final epoch.
Since `QuorumVerifier#containsQuorum(Set set)` does not check whether the
elements of argument `set` exactly represent participants, this pull request is
intended to ignore reported epochs and acks from observers for logical
consistency.
