   * @ngdoc service

   *
   * @description
   * The `$templateRequest` service runs security checks then downloads the provided template using
   * `$http` and, upon success, stores the contents inside of `$templateCache`. If the HTTP request
   * fails or the response data of the HTTP request is empty, a `$compile` error will be thrown (the
   * exception can be thwarted by setting the 2nd parameter of the function to true). Note that the
   * contents of `$templateCache` are trusted, so the call to `$sce.getTrustedUrl(tpl)` is omitted
   * when `tpl` is of type string and `$templateCache` has the matching entry.
   *
   * If you want to pass custom options to the `$http` service, such as setting the Accept header you
   * can configure this via {@link $templateRequestProvider#httpOptions}.
   *
   * @param {string|TrustedResourceUrl} tpl The HTTP request template URL
   * @param {boolean=} ignoreRequestError Whether or not to ignore the exception when the request fails or the template is empty
   *
   * @return {Promise} a promise for the HTTP response data of the given URL.
   *
   * @property {number} totalPendingRequests total amount of pending template requests being downloaded.
