* Output can be “shorten”, “refer”, “extend” and array of db field names.

* -refer: element ids are returned with element ids that were used in query.
* For example request item.get(output: refer, hostids: [1,2,3])) will return items with itemids and hostids.
* -extend: all db fields of element are returned (select *)
* -array of db fields: listed db fields are returned
