docs: Fix description of the leaky bucket algorithm in throttle.txt

- Water leaks from the bucket at a rate of 100 IOPS.
- Water can be added to the bucket at a rate of 2000 IOPS.
- The size of the bucket is 2000 x 60 = 120000
- If 'iops-total-max' is unset then the bucket size is 100 x 60.
- If 'iops-total-max-length' is unset then it defaults to 1 and the
size of the bucket is 2000.
- If 'iops-total-max' is unset then 'iops-total-max-length' must be
unset as well. In this case the bucket size is 100.
The bucket is initially empty, therefore water can be added until it's
full at a rate of 2000 IOPS (the burst rate). Once the bucket is full
