* refactor(l2geth): rename L1GasPrice to DataPrice

* feat(l2geth/rollup-gpo): allow execution price to be specified

* feat(l2geth/api): use the execution price instead of the historical gasprice

* feat(l2geth): allow configuring the l2 execution price

* fix(integration-tests): adjust gas costs to match 0-execution price

* fix(integration-tests): pin down l1 gas estimation costs to the expected values

* chore: add changeset

* fix(sync-service): adjust tests for the refactor

* feat(rollup-gasprice): make Rollup GPO methods thread safe

there's a race condition somewhere in hardhat which does not generate the artifacts
in the correct directory sometimes, causing our tests to fail with 'artifact not found'

* Add hardhat-gas-reporter package and base config

* Generate an output file from gas reporter when run in CI
Selectively enable gas reporter based on ENABLE_GAS_REPORT env var

* Add gas reports to integration tests

* fix: update hardhat to use correct solc url

* fix(core-utils): revert sentry/node version to 6.2.5

so that it's compatible with pino-sentry 0.7.0 aandrewww/pino-sentry#25

This was required because the hardhat upgrade removed any older versions
of the dependency which were still around and could be used.

* chore: add changeset

* ci: allow tests to be run on demand

* feat(hardhat-ovm): allow overriding the polling interval for the provider and its signers

The default is 50ms, which should make running the OVM tests smooth. If you want
to run tests against a remote node and do not want to overwhelm it, set the
parameter in the hardhat config's network

* chore: add changeset

* docs: add hardhat example

imported from https://github.com/ethereum-optimism/optimism-tutorial/

* ci: add deploy/deploy:ovm

* fix(contracts): wait for contracts to finish

workaround hardhat not generating build artifacts for both evm and ovm

* fix: use istanbul hard fork

* test(contracts): remove hardcoded post-state in nuisance gas test

this post state is not giving us much info, and it's hard to
update it or debug it when it does not pass for any reason
