      Called before making an attempt to retry a failed operation. Return 0 if an attempt needs to be made immediately.
      Parameters:
      retryCount - The number of times retried so far (0 for the first time).
      elapsedRetryTime - The elapsed time since the operation attempted. (in milliseconds)
