BUG 5656 : Entity ownership candidates not removed consistently on leadership change

This patch removes candidates for all downed members when entity ownership shard
leadership changes. This fixes a corner case where a leader/follower are both killed
simulaneously in a cluster which has greater than 3 nodes. In this case the old leader
does not have a chance to remove the killed follower. The new leader does know that
the follower is down so it can remove the candidates for all downed followers on
shard leadership change.
