Update Console.Log to show up in-line with hardhat node

[MexicanAce]

🌟 Feature Request

📝 Description

Currently, the smart contract console.log(...) statements only get printed to the console output/logs of the era_test_node binary when it's running. If you run yarn hardhat test --network hardhat, it will start the era_test_node run command in the background and you cannot see the console logs from the node in-line with your tests.

Hardhat Node repo: https://github.com/matter-labs/hardhat-zksync/tree/main/packages/hardhat-zksync-node

🤔 Rationale

It would be helpful to see the console.log lines from the Smart Contracts in-line with the console.log lines of the JavaScript tests of Hardhat

🖼️ Potential Solutions

1. Add a new console output mode for yarn hardhat test that will ONLY print out console.log lines from Smart Contracts. Then update the hardhat-zksync-node package to enable this flag by default AND tee the console output of the process running in the background.
2. Add a WSS endpoint where we push console.log lines. Update the hardhat-zksync-node to add a connection to the WebSocket endpoint and listen/print out any console.log lines that get emitted from era_test_node
