When set to non-zero values, the task remains in the queue for the specified seconds before
sent back to the worker when polled. Useful for the long running task, where the task is
updated as IN_PROGRESS and should not be polled out of the queue for a specified amount of
time. (delayed queue implementation)

@param callbackAfterSeconds Amount of time in seconds the task should be held in the queue
    before giving it to a polling worker.
