Title:
  When got a 403 response in glance panel, it will be redirect to log
  out

Status in horizon package in Ubuntu:
  New

Bug description:
  Based on implemented by angularjs framework, glance panel has such a problem:
  1. Set get_metadef_namespaces to '!' in glance/policy.json
  2. Log into horizon and direct to image panel
  3. Horizon will accept a response like:
     403 Forbidden: You are not authorized to complete get_metadef_namespaces action. (HTTP 403)"
     Due to the following code, web will be redirect to login page:
    function httpRedirectLogin($q, $rootScope, $window, frameworkEvents, toastService) {
      return {
        responseError: function (error) {
          if (error.status === 401) {
            var msg = gettext('Unauthorized. Redirecting to login');
            handleRedirectMessage(msg, $rootScope, $window, frameworkEvents, toastService);
          }
          if (error.status === 403) {
            var msg2 = gettext('Forbidden. Redirecting to login');
            handleRedirectMessage(msg2, $rootScope, $window, frameworkEvents, toastService);
          }
          return $q.reject(error);
        }
      };
    }

  I don't think it make sense to log out because the policy restricts
  this operation, but have no idea how to optimize. Hope anyone can give
  me suggestions.
