Ⅰ. Describe what this PR did
This PR introduces a new WASM plugin that enables tagging specific requests based on user-defined rules. The functionality is aimed at facilitating gateway-level gray scaling by tagging requests that meet certain criteria. This can be immensely useful for directing traffic and managing request flows in microservices architectures, especially for testing new features under controlled conditions.
