When starting from a fresh clone of the repo and running

```
make
make cannon-prestate
make devnet-up
```

We are left with a file changed in the tree at

```
packages/contracts-bedrock/deploy-config/devnetL1.json
```

This file is a bit annoying as it should not be checked in but shows as
an outstanding change.  The python script reads the original file, backs
it up, then rewrites that file with a new timestamp.

I'm not entirely certain why the timestamp needs to be rewritten, so
I've left that modification in place.  Instead, this change takes the
approach of moving the original file to a 'template' path, and ignoring
the modified file.  In this way there's no longer any need to constantly
create a backup and have the changes show up in a git diff.

Add cannon-prestate as prereq to devnet-up

The devnet-up ultimately requires the cannont-prestate target to have
already executed, or the script errors out.  Consequently, for someone
checking out the repo if they simply do a:

```
make && make devnet-up
```

Things still fail.  This change simply mirrors a similar check added to
the e2e Makefile.

op-program: Support prefetching l2-transactions

feat(indexer): wire up rpc client metrics

fix(indexer): Use subsystem rather than label to differentiate between l1/l2

ci: Require cannon-go-lint-and-test to pass before merging

op-wheel: add engine-api utils

Allow passing Config and Value to TxMgr

cannon: Prevent deadlock on pre-image reads

Reading a FileChannel that does not have a writer blocks
indefinitely. This occurs in cannon whenever the pre-image oracle
server shuts down prematurely. We add a new io.ReadWriter that can
detect when a FileChannel would otherwise block indefinitely.

fix(indexer): e2e test lifecycle

op-challenger: Use gzip encoded proofs and snapshots

Add ability to restrict the networks that op-node discovers peers on

op-challenger: Include the op-program host binary in docker image.

op-challenger: Detect already resolved games at startup

Update rollup-node-p2p.md

Avoids the need to manually specify the op-program binary to run as the cannon pre-image server.

Typo fix
