// Tasks sets the following headers:
//
// * `Content-Type`: By default, the `Content-Type` header is set to
// `"application/octet-stream"`. The default can be overridden by explicitly
// setting `Content-Type` to a particular media type when the
// [task is created](google.cloud.tasks.v2beta2.CloudTasks.CreateTask).
// For example, `Content-Type` can be set to `"application/json"`.
// * `Content-Length`: This is computed by Cloud Tasks. This value is
// output only. It cannot be changed.
//
// The headers below cannot be set or overridden:
//
// * `Host`
// * `X-Google-*`
// * `X-AppEngine-*`
//
// In addition, Cloud Tasks sets some headers when the task is dispatched,
// such as headers containing information about the task; see
// [request headers](/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers).
// These headers are set only when the task is dispatched, so they are not
// visible when the task is returned in a Cloud Tasks response.
//
// Although there is no specific limit for the maximum number of headers or
// the size, there is a limit on the maximum size of the [Task][google.cloud.tasks.v2beta2.Task]. For more
