Function expBackoff

Calculate exponential backoff/retry delay. Where attempts >= 1, exp > 1

Example

expBackoff(1000, 30000, attempts)
  ---------------------------------
   attempts | possible delay
  ----------+----------------------
       1    | 1000 to 2000
       2    | 1000 to 4000
       3    | 1000 to 8000
       4    | 1000 to 16000
       5    | 1000 to 30000
  ---------------------------------
Attempts required before max delay is possible = Math.ceil(Math.log(high/step) / Math.log(exp))
