feat[geth]: add gas pricer for congestion fees

contracts: add set-l2-gasprice task

Adds a dockerfile for the `gas-oracle` as well as adding it as
a service in the `docker-compose.yaml`. It is not enabled by
default due to memory issues in CI already happening occasionally
where the integration tests are oom killed.

The `gas-oracle` is configured with a key that owns the
`OVM_GasPriceOracle`.

This PR adds the `gas-oracle` to the Github Actions
workflow that is responsible for publishing the docker images.

This commit adds the `gas-oracle` which is an offchain entity
that sends transactions to L2 to update the gas price. It must
be configured with a private key as the `OVM_GasPriceOracle`
is owned.

The `gas-oracle` is added to the changesets setup.

Tests are included as well as CI. Dockerizing will happen
in a follow up PR.

The `gasprices` package implements the logic that updates
L2 gasprices on the Optimistic Ethereum Network.

feat: add workflow for running SNX test suite

chore(ci): Skip check files job on push events

Merge develop to master

ci(contracts): only run codecov if contracts package is modified

In order to skip running the CodeCov job when it isn't relevant, a new job was added to the ts-packges workflow. For a PR, this job identifies all the files modified between the base branch and the tip of the PR branch, and writes to a variable which can be used to decide if subsequent jobs should run.

Github Actions provides an easy method for achieving this at the level of a workflow, but not for specific jobs within a workflow.
