    Description

      Background: collections are no longer dropped immediately but renamed to a special drop-pending name and added to a task list in the ReplicationCoordinator.

      When the node sees the commit level (as dictated by the writeConcernMajorityJournalDefault) reach the drop op, it drops the drop-pending collection and removes the task from the list. Note that the proposed initial trigger for phase 2 (the drop op itself becomes known to be present on a majority of nodes) may not remain so in future versions; it may need to be delayed until a different condition.
