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".
