Delete documents from the database matching filter.

Filter can be specified either as part of the configuration or using an opt-in json-port.

See https://docs.mongodb.com/manual/reference/method/db.collection.deleteOne/ and https://docs.mongodb.com/manual/reference/method/db.collection.deleteMany/ for more details.
