The cloning phase of the movePrimary operation writes on the coordinator document the list of collections belonging to the database to be cloned. This information is serialized to a BSON object (i.e., collectionsToClone filed), and its size could potentially exceed the maximum limit. This would trigger a BSONObjectTooLarge error, that is considered retryable by the resilient cloning procedure of the movePrimary (see SERVER-74185).

The goal of this ticket is to handle this error by causing the operation to fail.
