coordinator:
    - Add config `ForgeDelay`: ForgeDelay is the delay after which a batch is
      forged if the slot is already commited.  If set to 0s, the coordinator
      will continously forge at the maximum rate.
    - Add config `ForgeNoTxsDelay`: ForgeNoTxsDelay is the delay after which a
      batch is forged even if there are no txs to forge if the slot is already
      commited.  If set to 0s, the coordinator will continously forge even if
      the batches are empty.
    - Add config `GasPriceIncPerc`: GasPriceIncPerc is the percentage increase
      of gas price set in an ethereum transaction from the suggested gas price
      by the ehtereum node
    - Remove unused configuration parameters `CallGasLimit` and `GasPriceDiv`
    - Forge always regardless of configured forge delay when the current slot is
      not yet commited and we are the winner of the slot
synchronizer:
    - Don't log with error (use warning) level when there's a reorg and the
      queried events by block using the block hash returns "unknown block".
