* 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.
* Fix index creation in cluster.
Simplify and correct error handling logic in ensureIndexCoordinator.
* After index creation, wait until index appears.
We wait until the Supervision has removed the isBuilding flag and
the coordinator has reloaded the Plan.
* More index handling fixes.
* Directly remove isBuilding in ensureIndexCoordinator (again).
* Fix catch tests by holding mutex shorter.
* Better mutex handling in ClusterInfo.

* Add JS tests
* temporary comment optimizations
* indexes are marked while still missing in Current
