Timeboost mode for nitro-testnode

[Tristan-Wilson]

This PR adds support for timeboost mode on nitro-testnode. It starts the bid-validator, autonomous auctioneer, deploys the ExpressLaneAuction contract, and starts the sequencer in Timeboost mode.

Since Timeboost is not yet merged into the master nitro branch, currently you will need to follow the following steps to run nitro-testnode in Timeboost mode. (If you had followed these instructions before note that this now no longer requires special steps with the nitro-contracts package as a version with timeboost is now released.)

• checkout nitro, branch: express-lane-timeboost
• In the nitro dir, go into the nitro-testnode submodule and check out timeboost-mode
  • From this directory, run ./test-node.bash --init-force --dev --l2-timeboost

When starting up, look for the line printing the token and contract address:

== Bidding token: $biddingTokenAddress, auction contract $auctionContractAddress

You can also find the auction contract and auctioneer address with the following command.

$ docker compose run --entrypoint sh sequencer -c "cat /config/sequencer_config.json" | jq .execution.sequencer
 ✔ Container nitro-testnode-geth-1  Running0.0s 
{
  "enable": true,
  "timeboost": {
    "enable": true,
    "auction-contract-address": "0x7DD3F2a3fAeF3B9F2364c335163244D3388Feb83",
    "auctioneer-address": "0x46225F4cee2b4A1d506C7f894bb3dAeB21BF1596"
  }
}

Users alice and bob have been pre-funded with some of the bidding token on L2 and can be used right away.

$ docker compose run scripts print-private-key --account user_alice

# make a deposit into the ExpressLaneAuction contract
$ docker compose run  --entrypoint /usr/local/bin/bidder-client timeboost-bid-validator --auction-contract-address 0x... --deposit-gwei 1000000000  --wallet.private-key <alice or bob private key, no 0x> --arbitrum-node-endpoint http://sequencer:8547

# make a bid for control of the next express lane round
$ docker compose run  --entrypoint /usr/local/bin/bidder-client timeboost-bid-validator --auction-contract-address 0x... --bid-gwei 1 --wallet.private-key <alice or bob private key, no 0x> --arbitrum-node-endpoint http://sequencer:8547 --bid-validator-endpoint http://timeboost-bid-validator:8547 

Commands for sending express lane transactions will be provided in future, see implementation and spec .

Changed the recommended nitro branch to express-lane-timeboost for now since it will get fixes.
