/**
* Adds on global error handling to an ajax request.
*
* If the ajax request returns with global errors, they will be displayed to the user, and the xhr promise will be rejected.
*
* If the error is something that can be fixed with a retry, the error will be displayed, but the xhr promise will NOT be resolved or rejected.
* Instead, progress callbacks will be called with 'stalled' as the argument. If the user attempts a retry, progress
* callbacks will be called with 'unstalled' and the result of a retry request will be used to resolve or reject the original xhr promise.
*
* @param jqXhr the ajax request to handle global errors for
* @param ajaxOptions the options object used in the call to $.ajax. These options are reused if the request needs to be retried.
