Adds parallel test execution to contracts to speed things up a bit.

deps: bump hardhat

Fixes a bug in the GasPriceOracle test suite that seems to only have had
an impact because hardhat got significantly faster between the current
iteration and the older one.

See release notes here:
https://github.com/NomicFoundation/hardhat/releases/tag/hardhat%402.9.0

This is a performance release, so it is good to upgrade here
to improve the time of CI. The compilation happens in parallel
with this release, as well as tests being able to be ran in parallel.

We do not make use of any forked network tests currently, but
this PR does help to speed up that usecase as well.

fix(rhc): typo in healthcheck docker-compose

Version Packages

Fixes a typo in the primary docker-compose file. replica-healthcheck
should be replica_healthcheck to conform with the style used everywhere
else.

build(deps): bump minimist from 1.2.5 to 1.2.6

ci: Add CircleCI config

gas-oracle: allow configurable base fee poll interval

This commit adds a new config option that can be
configured via argv with `--l1-base-fee-epoch-length-seconds`
or an env var `GAS_PRICE_ORACLE_L1_BASE_FEE_EPOCH_LENGTH_SECONDS`.
It defaults to 15 seconds. Ideally the implementation uses a
duration flag instead of a uint64 flag, but that would be a
breaking change for the config and this service will be
deprecated in the future with the release of bedrock.

By setting this value to a larger number, we are able to update
the L1 base fee that is held in the L2 state less often.
This will save the sequencer money, because it needs to
front the costs of submitting these transactions.

Bumps [minimist](https://github.com/substack/minimist) from 1.2.5 to 1.2.6.

feat(ct): overhaul deployment process

deps: update l2geth-exporter to use go-ethereum v1.10.16

deps: update bss-core to go-ethereum v1.10.16

fix(rhc): fix bug in healthcheck dockerfile

Adds a single simple test to confirm that the healthcheck metrics server
is running. If the server is not running then the healthcheck server
likely did not start correctly and there might be an issue in the docker
container.

Updates the replica-healthcheck service to cleanly catch connection
failures in the target and reference nodes. When a failure is detected,
a metric will be incremented and the failure will be logged.

Fixes a bug in the replica-healthcheck dockerfile. Also includes
replica-healthcheck as part of the ops setup by default to make this
stuff easier to catch and debug in the future. We will likely still want
to add integration tests that query the metrics defined in the
replica-healthcheck to confirm that everything is working as expected.
