Configure block rewards on a QBFT network deployment

[antonydenyer]

Enable block rewards to be configurable

{
  "config": {
     ...
     "qbft": {
       "blockPeriodSeconds": 2,
       "blockReward": "5000000000000000"
     },
     "transitions":  [
       {
         "block": <FutureBlockNumber>,
         "blockReward": <NewValue>
       }
     ]
  },
  ...
}

The rewards should go to the miner coinbase as normal
