Currently, the $listClusterCatalog stage is an alias to an internal pipeline. This pipeline aims to merge the local and the global catalogs to offer an extended version of the listCollections command.

The issue is that having an internal pipeline complicates the consistent retrieval of both catalogs. It's even too complex to read at the same point in time on different collections of the global catalog.

Converting the $listClusterCatalog stage into an actual DocumentSource stage will pave the way to achieve consistency between the two catalogs, and will make it possible to read all the collections in the global catalog at the same point in time.
