      In order to implement the 2-phase setFCV mechanism described WRITING-7769 and in particular the DDL patch-up steps that follow, a mechanism to wait for all ongoing ShardingDDLCoordinators to finish is needed. This ticket is to implement it.

      Preventing new coordinators from starting is outside the scope of this ticket.
