      The goal of this new config.collectionCriticalSections shard-local collection is to track which collection critical sections are taken and by which DDL operation.

      This is needed to be able to resume DDL operations on step-up.

      We need the following fields:

      {
   nss: namespacestring,
   reason: object,
   additionalInfo: object, [OPTIONAL]
}
