Integration/regression tests

[han-so1omon]

What needs to be done

Run integration/regression tests with local testnet on pull request to master

Why it needs to be done

There are currently no automated integration tests, and as a result there are too many day-zero bugs

Acceptance Criteria

• Establish integration/regression tests using containerization tools like DIVE and Docker Compose. There must be containers for the ICON chain with CPS contracts as well as for the React CPS frontend
• Run the smart contract integration tests as part of the pipeline. If necessary, update the smart contract integration tests
• Run the frontend integration tests as part of the pipeline
• When a pull request is submitted to master, a Github Action is triggered to run the integration/regression tests, where all integration tests must pass to yield Success
