Host-Based Pipeline Deployment for the Debezium Platform

The Debezium Management Platform currently deploys pipelines only to Kubernetes. This project adds host-based deployment support, enabling users to deploy Debezium Server pipelines to bare-metal servers and cloud VMs via SSH and Docker. The implementation integrates into the platform's existing event-driven architecture by adding a new EnvironmentController for host targets, an SSH-based provisioning service that validates and prepares remote hosts, a lightweight agent deployed on each host for managing the Debezium Server lifecycle via REST APIs, and a status polling mechanism for monitoring deployments. Key deliverables include the host registration API, automated provisioning with remediation, the Debezium Host Agent, Docker-based deployment engine, config drift detection, and comprehensive integration tests using Testcontainers.
