Lars Maier dd07d74d69 [devel] Bug fix/bad leader report current (#7585) 
* Bug fix 3.4/bad leader report current (#7574)
* Initialize theLeader non-empty, thus not assuming leadership.
* Correct ClusterInfo to look into Target/CleanedServers.
* Prevent usage of to be cleaned out servers in new collections.
* After a restart, do not assume to be leader for a shard.
* Do nothing in phaseTwo if leader has not been touched. (#7579)
* Drop follower if it refuses to cooperate.

This is important since a dbserver that is follower for a shard will
after a reboot think that it is a leader, at least for a short amount
of time. If it came back quickly enough, the leader might not have
noticed that it was away.
