Take replace generator in `ibc-test` with the ckb-cli about the contract development

[ashuralyk]

Summary

the generator in ibc-test module should be replaced with ckb-cli

Problem Definition

the contract deployment through generator is not compatible with the normal way, e.g. via ckb-cli, generator module assumes the deployer should be the miner of dev-chain and its private key is exposed right in the source code, so we should use ckb-cli to make deployment process instead
