Add a "Limit" to Delete and Bulk Delete operations
Deleting tens of millions of documents can have a big impact on the performance of the Clusters, even using Bulk Delete. A "Limit" must be added to Delete and Bulk Delete to let us limit the number of operations, making sure we do not kill the Clusters' performance.

MongoDB 4.2 Distributed Transaction with Arbiter
