Integration Test Suite utility

was created with aims to:

• Provide a simple way to set up and run integration tests
• Able to run integration tests in parallel
• Environment nearest to E2E testing
• Initialize a chain with CometBFT node to fully functional testing
• Init chain with pre-defined set of validators and wallets, easier to trace and debug
• Able to set up test for Json-RPC server

Notes:

• To get historical data correctly, need to use query clients/rpc backend/... at corresponding height

Weak points:

• Only support Linux & MacOS, possible to make it compatible with Windows by enhance the TemporaryHolder functionality
• Easy to get import circle error, need a dedicated folder for integration test
