'Reactivates the specified task.
Reactivation makes a task eligible to be retried again up to its
maximum retry count. The task\'s state is changed to active. As the task
is no longer in the completed state, any previous exit code or
scheduling error is no longer available after reactivation. This will
fail for tasks that are not completed or that previously completed
successfully (with an exit code of 0). Additionally, this will fail if
the job has completed (or is terminating or deleting).
