ClusterDiscoveryActor instance on node that lost leader election should subscribe to cluster events and in case it's host node was appointed to be the new leader of Akka cluster should transition to leader role: register itself as leader in etcd and update the seed list according to it's best knowledge. This will ensure that new nodes will be able to use discovery properly after the original leader leaves the cluster.

ClusterDiscoveryActor should listen ClusterDomainEvent rather than MemberEvent when it is Follwer because LeaderChanged event is not MemberEvent.
