Add contract deployment scripts

[smartcontracts]

Description

This PR adds simple contract deployment scripts to the contracts package.

API for deployments is:

const deployAllContracts = async (
  config: RollupDeployConfig
): Promise<AddressResolverMapping>

Where RollupDeployConfig is defined as:

interface RollupDeployConfig {
  signer: Signer
  rollupOptions: {
    gasLimit: number
    forceInclusionPeriod: number
    owner: Signer
    sequencer: Signer
    l1ToL2TransactionPasser: Signer
  },
  addressResolverConfig?: {
    factory: ContractFactory,
    params: any[],
    signer: Signer
  },
  contractDeployConfig?: Partial<ContractDeployConfig>
  dependencies?: ContractFactoryName[]
}

Where contractDeployConfig is a partial of ContractDeployConfig is an object mapping factory names to deploy options:

interface ContractDeployConfig {
  L1ToL2TransactionQueue: ContractDeployOptions
  SafetyTransactionQueue: ContractDeployOptions
  CanonicalTransactionChain: ContractDeployOptions
  StateCommitmentChain: ContractDeployOptions
  StateManager: ContractDeployOptions
  ExecutionManager: ContractDeployOptions
  SafetyChecker: ContractDeployOptions
  FraudVerifier: ContractDeployOptions
  ContractAddressGenerator: ContractDeployOptions
  EthMerkleTrie: ContractDeployOptions
  RLPEncode: ContractDeployOptions
  RollupMerkleUtils: ContractDeployOptions
}

Since it's a partial, you can provide a subset of these contracts and the rest will be deployed as their default versions.

And each ContractDeployOptions is:

interface ContractDeployOptions {
  factory: ContractFactory
  params: any[]
  signer: Signer
}

dependencies is simply an array of contract factory names to deploy. If not provided, the function will deploy all contracts.

Returns an object of the form:

{
  addressResolver: Contract,
  contracts: { [name: string]: Contract }
}

You can also use the second helper function deployAndRegister to overwrite an address in the AddressResolver and replace the contract on the fly:

const deployAndRegister = async (
  addressResolver: Contract,
  name: string,
  deployConfig: ContractDeployOptions
): Promise<Contract>

Where addressResolver.getAddress(name) will then point to the contract deployed based on the provided deployConfig.

Questions

• Does the API look ok?
• Any additions that would make this more useful?
