Agent-based deployment in Release Management

This post introduces agent-based deployment in Release Management, a new capability for orchestrating multi-machine deployments and performing rolling updates with high availability. It defines 'Deployment Groups' as logical groupings of target machines with agents installed directly on them, representing physical environments. The post details the process of creating deployment groups, authoring release definitions with various deployment configuration options (one target at a time, half, all, custom), and viewing live logs during deployment. It also highlights simplified agent bootstrapping via cmdlets and planned enhancements for Azure resource integration.
