test(tendermint): migrate to local/offline containerized testnets (#2128)

- Run local ATOM testnet in container for integration tests
- Run local NUCLEUS testnet in container for integration tests
- Add IBC relayer node in container connected to both testnets
- Include test coverage for Tendermint - ETH swap
- Use .docker/container-state for consistent testnet initial state
