@brief removes multiple documents by their keys
collection.removeByKeys(keys)
Looks up the documents in the specified collection using the array of keys provided, and removes all documents from the collection whose keys are contained in the keys array. Keys for which no document can be found in the underlying collection are ignored, and no exception will be thrown for them.
The method will return an object containing the number of removed documents in the removed sub-attribute, and the number of not-removed/ignored documents in the ignored sub-attribute.
