/// 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).
