      The goal of this ticket is to introduce new metrics in server status output to track the usage of collection critical section. 
      The collection critical section is used to temporarily block CRUD operations on a collection while a DDL or data migration operations are committing collection metadata changes to global catalog and shard-local catalog.

      Ideally, this ticket should be executed together with SERVER-99934.
