The blockhashes can be non deterministic because there is not a global
consensus in the existing deployment of the optimism network, instead
each node runs with `--dev 0` meaning that it auto mines transactions
itself. Previously, block hashes were non deterministic due to a
different clique signing key being used but that was fixed so that
a deterministic key is used for all nodes.

This fixes the possibility of the block extradata being different which
would result in different block hashes. The extradata is hard coded
to be the same value as the release @eth-optimism/l2geth@0.4.6. In
version 0.4.7, the underlying Dockerfile pulled in a patch release of
the Go runtime which caused the extradata field to become different.
The extradata field by default is the version of the software (which
cannot change until the next regenesis), "geth", the go runtime version
and the operating system.

This will require a resync to make block hashes deterministic across the
network.

l2geth: fee too high error message

Version Packages

Update the error message returned when the fee is too
high to return the correct multiplication. It should be
the expected fee * the fee threshold up.

feat: set owner task

Creates a task that can set the owner of any contract that is `Ownable`.
It defaults to attempting to set the address of the `OVM_GasPriceOracle`
on L2. The following config options must be set:

- `CONTRACTS_RPC_URL`
- `CONTRACTS_DEPLOYER_KEY`

It can be invoked like so:

```
$ npx hardhat set-owner --owner 0x..
```

On L2 networks that do not enforce transaction fees, the
`--transaction-gas-price 0` config option may be used for
convenience.

This script also supports Ledger with the `--use-ledger` flag.
It defaults to deriving a key at the `ethers.utils.defaultPath`.

l2geth: prevent too low of fees from getting through

There was a bug in the floating point math that allowed

This PR fixes that bug as well as adds additional test

l2geth: fix bad flag parsing

The parsing of the `ROLLUP_FEE_THRESHOLD_UP` and
`ROLLUP_FEE_THRESHOLD_DOWN` config options were set to be boolean flags
instead of float64 flags. The config flags wouldn't parse if a float64
was used as a bool flag.

l2geth: only accept txs with exact nonce

Dynamically generate predeploy contracts markdown

This PR makes it so that the sequencer will
only accept transactions if the nonce exactly
matches what is in the state. This is because the
mempool in upstream geth has different rules than
what l2geth needs.

This prevents issues with local nonce managers that
send transactions with a too large of nonce and
end up having all of the transactions revert since
the transaction is still accepted but reverts
in the OVM

The sequencer will reject transactions when the fee
is too large to prevent users from accidentally sending
transactions with a huge fee.

This PR adds an actionable error message for when
the fee is too large.
