/**
 *
 *
 * <pre>
 * HTTP request.
 * The task will be pushed to the worker as an HTTP request. If the worker
 * or the redirected worker acknowledges the task by returning a successful HTTP
 * response code ([`200` - `299`]), the task will be removed from the queue. If
 * any other HTTP response code is returned or no response is received, the
 * task will be retried according to the following:
 * * User-specified throttling: [retry configuration][google.cloud.tasks.v2.Queue.retry_config],
 *   [rate limits][google.cloud.tasks.v2.Queue.rate_limits], and the [queue's state][google.cloud.tasks.v2.Queue.state].
 * * System throttling: To prevent the worker from overloading, Cloud Tasks may
 *   temporarily reduce the queue's effective rate. User-specified settings
 *   will not be changed.
 *  System throttling happens because:
 *   * Cloud Tasks backs off on all errors. Normally the backoff specified in
 *     [rate limits][google.cloud.tasks.v2.Queue.rate_limits] will be used. But if the worker returns
 *     `429` (Too Many Requests), `503` (Service Unavailable), or the rate of
 *     errors is high, Cloud Tasks will use a higher backoff rate. The retry
 *     specified in the `Retry-After` HTTP response header is considered.
 *   * To prevent traffic spikes and to smooth sudden increases in traffic,
 *     dispatches ramp up slowly when the queue is newly created or idle and
 *     if large numbers of tasks suddenly become available to dispatch (due to
 *     spikes in create task rates, the queue being unpaused, or many tasks
 *     that are scheduled at the same time).
 * </pre>

   * The task will be pushed to the worker as an HTTP request. If the worker
   * or the redirected worker acknowledges the task by returning a successful HTTP
   * response code ([`200` - `299`]), the task will be removed from the queue. If
   * any other HTTP response code is returned or no response is received, the
   * task will be retried according to the following:
   * * User-specified throttling: [retry configuration][google.cloud.tasks.v2.Queue.retry_config],
   *   [rate limits][google.cloud.tasks.v2.Queue.rate_limits], and the [queue's state][google.cloud.tasks.v2.Queue.state].
   * * System throttling: To prevent the worker from overloading, Cloud Tasks may
   *   temporarily reduce the queue's effective rate. User-specified settings
   *   will not be changed.
   *  System throttling happens because:
   *   * Cloud Tasks backs off on all errors. Normally the backoff specified in
   *     [rate limits][google.cloud.tasks.v2.Queue.rate_limits] will be used. But if the worker returns
   *     `429` (Too Many Requests), `503` (Service Unavailable), or the rate of
   *     errors is high, Cloud Tasks will use a higher backoff rate. The retry
   *     specified in the `Retry-After` HTTP response header is considered.
   *   * To prevent traffic spikes and to smooth sudden increases in traffic,
   *     dispatches ramp up slowly when the queue is newly created or idle and
   *     if large numbers of tasks suddenly become available to dispatch (due to
   *     spikes in create task rates, the queue being unpaused, or many tasks
   *     that are scheduled at the same time).
