[Duo Pro] AI Generated Code Reviews using AI capabilities

Proposal

Code reviews are essential for maintaining high-quality codebases but can be time-consuming and sometimes inconsistent due to varying levels of expertise and reviewer fatigue. This can lead to slower development cycles and missed opportunities for educational feedback

Propose the integration of an AI-driven feature within GitLab that automatically generates code reviews. This feature will leverage advanced AI algorithms to analyze code submissions against a comprehensive set of quality metrics, including style conformity, potential bugs, and performance optimizations. By providing immediate, consistent, and insightful feedback, this aims to enhance the efficiency of the code review process, ensuring developers receive valuable guidance that helps them improve their code quality over time.
