        Computes a method that would delay ticks using an exponential backoff. Will keep retrying until an expiration time. The last attempt will start before the expiration time.
        Parameters:
        expireAt - absolute time in millis that specifies when to give up.
        firstBackoff - the delay of the first backoff
        maxBackoff - the max backoff
        jitterFactor - the jitter factor in [0, 1]
        executor - the executor used for the delay
        Returns:
        the function
