I only set `OpNode.server` to the created server if it starts up
successfully. This alleviates an error where if creation succeeds,
but startup does not, we attempt to stop the server which panics.

This also adds logging to indicate that initialization failed. This
logging primarily benefits users who call `node.New` directly rather
than end users because there is already logging in the main function.

I tested this manually with op-e2e & was able to reproduce the error &
confirm that it is fixed.

* Allow customization of signer function

* Switch to using function from op-service

* Small cleanup

* Support passing SignerFn to BatchSubmitter contructor

* Switch to signer factory methods

* Update op-service dep in op-e2e too

* go mod tidy

* go mod tidy

* Cleanup confusing duplicate variable naming

feat(ctb): last OptimismPortal nitpicks

ci: yarn clean before build with metadata

A few final nitpicks for the OptimismPortal. Cleans up a couple comments
and improves some formatting.

contracts-bedrock: bump L1 contracts to 1.0.0

feat(ctp): Optimist mainnet deploy

feat(fd): have fault detector wait for providers

Deployment artifacts for the mainnet deployment of the Optimist
contracts.

Bumps the semver of the L1 contracts to `1.0.0`.
We haven't been tracking versions of things up to this point.
This prepares them for a production ready release.

feat(ctp): Optimist goerli deployment

Committing Optimist contract deployments for optimism-goerli. Contracts
are all verified.

feat(contracts-periphery): Make optimist deploy scripts safer

maint(ctp): clean up Optimist comments

test(ctb): port L2ERC721Bridge tests

maint(ct): remove deprecated deployments

feat(contracts-periphery): Clean up optimist tests

ctp: fix version assert in deploy scripts

Cleans up comments inside the Optimist NFT.

Updates the fault detector to wait for its L1 and L2 RPC providers using
a new utility function in common-ts. This will prevent errors that users
currently experience with the fault detector.

feat(ctb): inline verification function

Removes deprecated contract deployments to avoid confusing users who are
looking at these deployment folders. Also updates the markdown
generation script to remove an incorrect notice for Goerli.

ctp: delete dead network artifacts + config

feat(ctb): break out token interfaces

feat(contracts-periphery): Add authors to optimist.sol

ctp: deterministic deployment optimist proxy

ctp: AttestationStation deterministic proxy

Inlines verifyInclusionProof because it was only being used once.
