how to add timeout to webix.ajax call?

as title

There is no a native solution, we will add an ability to define AJAX timeout in oncoming Webix 2.5

Currently you can use

webix.attachEvent("onBeforeAjax", function(mode, url, params, xhr){
    xhr.timeout = 3000;
    xhr.ontimeout = function(){ /*do something*/ };
})
