> We removed most of non-async calls, but there's a few that still need to be converted.
> Non-async calls are problematic.  If the request is not satisfied for whatever reason
- say wifi drops, it completely blocks the browser tab (you cannot even close the browser
tab in Chrome):
> ambari-web/app/controllers/wizard.js:
>   loadServiceComponents: function () {
>     return App.ajax.send({
>       name: 'wizard.service_components',
>       sender: this,
>       data: {
>         stackUrl: App.get('stackVersionURL'),
>         stackVersion: App.get('currentStackVersionNumber'),
>         async: false
>       },
>       success: 'loadServiceComponentsSuccessCallback',
>       error: 'loadServiceComponentsErrorCallback'
>     });
>   },
> ambari-web/app/utils/ajax/ajax.js:
>   'router.authentication': {
>     'real': '/clusters?fields=Clusters/provisioning_state',
>     'mock': '/data/clusters/info.json',
>     'format': function() {
>       return {
>         async: false
>       };
>     }
>   },
> ambari-web/app/utils/polling.js:
>   setRequestId: function () {
>     if (App.get('testMode')) {
>       this.set('requestId', '1');
>       this.doPolling();
>       return;
>     }
>     var self = this;
>     var url = this.get('url');
>     var method = 'PUT';
>     var data = this.get('data');
>     $.ajax({
>       type: method,
>       url: url,
>       async: false,
>       data: data,
